The problem is already fixed...sort of. I made some code a long while ago
that fixed all PowerBook video problems. Unfortunately, all of the changes
haven't quite made it into the source yet. This is because some of the
changes were a little klugey and really should be fixed properly first
rather than being "worked around" via a hack.

Try test booting with the latest booter (1.11 something) and a brand new
1.3 Alpha kernel. You can do this without partitioning anything, just
get the booter and the kernel and tell the booter to load the kernel from
a MacOS file. The kernel should boot and if it's sucessful will ask for
a root partition (which you won't have but at least you'll know it gets
that far).
