Which version of FreeBSD are you trying to install? Judging from the
error message, I guess it must be one of 2.1.X's or 2.2-ALPHA.

My first suggestion is to try either 2.2-BETA or 3.0-970118-SNAP. 
(SNAP is better as far as keyboard access code is concerned.)  They
use entirely new keyboard I/O routines, and the new routines are
expected to work better than the ones which they replace... well, 
in theory :-)

However, if your Compaq luggable has a really unusual keyboard and a
keyboard controller, even they may not work though ;-<

Commenting keyboard reset code out may or may not work; I really don't
know.  The purpose of keyboard reset is to detect the keyboard,
initialize it and place it in the known state, AFAIU.
