The one on the web page ? Yes, the one on your web page (vmlinux-2.2.17pre9-ben1).

It doesn't work for me (pressing these keys are a no-op, which is actually better than powering off). I used your kernel with 'append="adb_buttons=52,76"'.

Good idea. Should make it's way into the yaboot-FAQ since you don't need to repartition. > >Somewhat working.

If you disable acceleration on your text consoles, X works right. This might already have been fixed (SuSE's beta X Server is of Aug'99). And the fact that the virtual resolution is 800 5222 might make it impossible to find your login window (which is centered) 8-o Apart from that I didn't succeed to access the mouse.

Good to hear, seeing 'my Mac partition has been destroyed' by casual Linux users on this list gives me shivers. This often hides a personal tragedy. Christof ** Sent via the linuxppc-dev mail list.
