Linux/AXP keyboard not responding (PATCH)

After a day (and a night ;)) of playing around, we finally have an Alpha
running Linux again (2.0.8). A Jensen...

Anyway, when booted with a 1.3.90 kernel it complains about the keyboard
(something like "initialize_kbd: reset kbd failed, not POR") but it works
fine. A 2.0.8 kernel also complains but fails to initialize the keyboard
completely.

I patched drivers/char/keyboard.c not to just give up after an error; I
don't think this breaks anything, it just gives some more errors than
usual when there really isn't a keyboard connected. At least now I can
use the console keyboard again.

I don't know if this is a Jensen only thing, but the patch is here anyway
for those interested:
