After a long time of waiting Gentoo is now finally installed on my PowerMac 7300/166 (yeah 166Mhz!) but I have some problems:

1) I have configured Xorg to use fbdev with 15bit and 640x480. I have a VGA monitor attached to the internal video board. My question is: How can I make fbdev support higher resolutions like 800x600 or even 1024x768. The internal card has 2MB of ram which should be enough for the wanted resolutions. I have been playing around with fbset but got stuck: I dont know how to correctly set up these screen parameters. Any hints on how to find some examples?

2) I have an old voodoo2 board lying around (obviously PC hardware). I know there is a kernel level fbdev driver for this kind of cards. Can I get this thing to work as my primary display? (AFAIK it has a 4MB framebuffer)

3) I have installed a USB card with a VIA chip on it which gets correctly identified by the uhci_hcd driver but as soon as I plug in a device something goes wrong and the kernel halts the driver. I have tried to run it with the OHCI driver but then it shows no devices. The packaging of the card said it would be compatible with MacOS X. Thats why I though Linux/PPC can handle it too. Here is the kernel output when I attach a device:
uhci_hcd 0000:00:0f.0: host controller process error, something bad happened!
uhci_hcd 0000:00:0f.0: host controller halted, very bad!

If you want me to add any information to help finding solutions just let me know.

Any help is appreciated!
