We should do it the day we don't have anything other to do ;)

True, but in this context it's more or less equivalent to sparc ( the 
keyboard/mouse hardware is shared between oldish sparc64 and later sparc, and 
recent sparc64 hardware uses USB )

Yeah, I did the adbkbd bit mostly so I could use a USB number pad on a macppc 
laptop in X without fiddling with xorg.conf

I was wondering that myself, in theory we should be able to generate native to 
USB translation maps from the native maps in the drivers in question and 
ukbd. In real life I found it less cumbersome to just write the ADB->USB 
table by hand.

Hmm, it should be possible to generate X11 keymaps from kernel keymaps.

have fun
