I'm wondering what the smartest way is to do this.

My current idea is this:
~15gb hda ext3 gentoo w/hfs+ read/write compiled to kernel
~15gb hdb hfs+ OSX w/ext3 (2) read/write module installed

Questions:
- Is hfs+ read/write support stable enough to use full time?
- Are there ppc linux drivers for the video card the iBook G4 uses and are they difficult to install?
- Is it difficult to get openfirmwire to boot GRUB and establish a dual booting gentoo/osx option?

Hmm, I just read the FAQ talking about how there is currently no hardware accel in X for the powerbooks, I would much suspect the same for the iBooks. That blows hard. Maybe I should just stick to select x86 hardware and leave OS X on my iBook. :roll:

xorg works fine on my iBook G4 12".
www.tuxmobil.org or www.linux-on-laptops.com could help you.

i think hfs+ rw support is still experimental but developpers always need testers ;)
i read somewhere that mac os x doesn't support linux file systems, but i don't know more about that. It might be outdated.

Not sure u can use grub on a ppc, but follow the ppc-handbook to dual-boot with yaboot.

Yes. Under 2.6.7 it is perfectly stable for me and has been so for more than a year. I access it daily to play music etc. and have transfered files bigger than 1GB back and forth without problems.

Also, you can mount, read and write Ext3 Volumes under MacOS X with http://sourceforge.net/projects/ext2fsx/. Last I tried it worked very well, but I'm not using ext3 partitions anymore as ReiserFs and XFS are much faster.

Yes, and it's not difficult. Take a look here for ready-to-use working configs for your iBook:

Grub is an x86-only bootloader. On Macs we use yaboot. Its configuration is quite similar to lilo and very well documented. Check the Gentoo installation Handbook or search the PPC forum here. Yaboot autoconfigures all OpenFirmware variables so it requires no extra setup from you except editing /etc/yaboot.conf.

What I want to do is keep macosx on the internal HDD, but load Gentoo-PPC onto an external firewire/usb drive
can I do that and boot from the external??

As far as I know that should be possible since Open Firmware supports booting off external hard drives.

Another way to setup your parititions would be to have Reiserfs for / and everything else and then set your /home as HFS+.

I can get hardware acceleration on my iBook G4. You just need to enable the DRI and radeon modules into the kernel.

You should be able to setup yaboot fine as long as read and follow the installation handbook.

Kethinov: 15GB is way more than necessary for linux. I have 6GB total for linux, and that is 70% unused. Also, unless you like living on the edge, avoid reiserfs and XFS and stick with ext3.

Your iBook has a radeon in it; xorg has pretty good radeon support. The only powerbooks with issues are aluminum ones with GForce cards in them. That is because NVidia only releases binary drivers, and only for x86.
