Subject[patch] Franz Sirl's final PPC input conversion part

ChangeSet@1.512, 2002-08-21 22:30:28+02:00, Franz.Sirl-kernel@lauterbach.com
Hi Vojtech,
I noticed you just pushed the pc_keyb.c removal to linux-input, here is the
PPC part of it that removes now superflous stuff. The small change in
keyboard.c is a bugfix from 2.4 and ruby that didn't make it into 2.5 yet.
Franz.
