It's much less complicated than you probably think. The problem is  
that on some Macs the keyboard devalias doesn't point to an actual  
device but /ps{eu|ue}do-hid/keyboard and in those cases we can only  
guess what the keyboard actually is. On yours and mine it's obvious -  
there is no ADB support present so it must be USB. On others it isn't  
quite as easy, for instance almost(?) all powerpc-based Apple laptops  
have ADB keyboards built in but USB keyboards may be present, in this  
case we must default to ADB even though the keyboard devalias points  
to /psuedo-hid/keyboard ( yes, Apple's typo )

I'll hopefully have time to hack up a workaround in the near future -  
do you have a way to netboot your G4 or do you have room for an  
APPLE_UFS partition in order to boot a kernel I'd send you? ( you can  
install pretty much entirely from MacOS X, not sure if MAKEDEV would  
work properly though )

have fun
Michael
