Now i am a PC and need help moving into the mac world.

Code:
the specs:
  15.2-inch TFT Display
  1280x854 resolution
  1.67GHz PowerPC G4
  512MB DDR333 SDRAM(will add more later)
  80GB Hard Drive
  ATI Mobility Radeon
  9700 (128 MB DDR)
  Backlit keyboard
  Gigabit Ethernet
  FireWire 400 & 800
  Analog audio in/out
  DVI & S-Video out 


I would really like to dual boot and I am just wondering if you guys could give me some pointers on how to go about installing gentoo on this powerbook.

I have installed gentoo before, but only on a x86 system.

I am just wondering what i need to lookout for when i am installing the gentoo on the powerbook and make sure i get everything working.

Read the ppc gentoo installation handbook :)
http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml

Pay careful attention to the partitionning and boot loader sections as they differ from x86 since Macs do not use the PC BIOS to boot.

Then if you have specific questions, feel free to ask.

From the specs you've posted it looks like a new Powerbook, like the one I have. You need to be very careful as some of the hardware isn't properly supported at the moment. See https://forums.gentoo.org/viewtopic-t-304505.html

The dual boot is easy. I had a triple boot going for a while--OS X, OS 9, and linux. I don't really like yaboot's style that much, but as a bootloader, it works; just follow the directions in the handbook. I once even installed it for the purpose of dual booting OS X/OS 9 because I didn't like the way OS X handled it.

I've learned some interesting things about optimization flags on the ppc. If you use -O2 instead of -O3, make sure to add "-frename-registers" in your CFLAGS too (unless you want to do debugging, which is not likely). The ppc chips have a TON of registers and benefit greatly from this.

I haven't gotten wireless or a touchpad to work, but then I haven't tried. I will say one thing--I've never had any hardware on my ppc that I was unable to get to work. I even got sound working on my PPC before I ever got it working on x86.

From what I've found, you have two advantages to buying a mac:

(1) Apple's hardware is very solid. It is sort of like buying IBM, or buying an Intel-made server or something; you pay a premium, and then stuff just doesn't break. The only thing I ever had break that was sold by apple was a monitor, and I worked that thing for years.

(2) The ppc architecture is sweet. For linux, I find that it handles multitasking way better than the feeble x86 architecture. I have a G3 that outperforms a pentium 4 at many tasks, especially doing something like compiling, while running (and doing something with) a database server, and browsing the web on that machine. The P4 buckles and gets choppy; the ancient G3 is certainly not blazingly fast, but it stays smooth and doesn't really slow down that much, somehow.

BTW my friend got wireless and a touchpad to work on Debian, with a second generation iBook (the boxy ones, 12-inch). So I know it can be done.

Airport Extreme cards don't work in Linux. The non-extreme (802.11b) do work well.

Don't expect Airport Extreme to work anytime soon. The specs are not available by the company making them and nobody have reverse-engineered them.

The thread https://forums.gentoo.org/viewtopic-t-304505.html evokes some major problems, but apparently they seem to be about to be solved (regarding to the mouse).
However, you should not expect to get the DRI or airport working anytime soon. I have been waiting for 14 months and still these are not available... :(

You could wait for 10 years and still not get Airport Extreme support. The thing is that the specs are not available and unless someone reverse engineer the card and write a driver, there will be none.

In the x86, they use the Windows driver + wrapper code. I am not sure how feasible it would be to do that around the OS X driver.
