2.4 users are not innocent :-). As I said, just don't turn on
CONFIG_ADBMOUSE. I'm doing that right now, cause the kernel uses linux
keycodes already internally now, and they will show up externally somewhere
during 2.5, so doing it for 2.4 with backwards compatibility on by default
is the best thing to do.

I fixed that in my tree too, just got the condition in pmac_setup.c wrong,
it should be if (!keyboard_sends_linux_keycodes) ..., just a typo, will be
fixed later today.

See above, switching /proc/sys/dev/mac_hid/keyboard_sends_linux_keycodes to
1 and then back to 0 probably fixes it.

Mouse button emulation works for me and it works in both keycode modes, in
2.4 the adb_buttons kernel arg is gone though.
