How do I do that? Can one of you prepare a diff against Bens current
tree? He is at pre10 since last night.

My machine has these data:
cpuinfo:
clock           : 291MHz
machine         : PowerBook
motherboard     : AAPL,PowerBook1998 MacRISC
lspci -n:
00:11.0 Class 0300: 1002:4c47 (rev 80)

This is what 18pre4-ben1 reports:

I have currently no access to other PowerBooks, only the Wallstreets
need the patch. iBook works fine and Lombard should also work.
There is still that init problem, but it is less worse than a hard
crash.
