Boot failure with kernel 2.6.15 on G4

[Magnus Käck <magnusk2@telia.com>]

I recently installed testing ppc on my mac mini with no problems, but 
just after I upgraded and now I get this during boot.

i8042.c: No controller found.
FATAL: Error inserting i8042 
(/lib/modules/2:6.15-1-powerpc/kernel/drivers/input/serio/i8042.ko): No 
such device
ALERT! /dev/hda6 does not exist. Dropping to shell!
