CVS commit: src/sys/dev/ic
Module Name: src
Committed By: drochner

src/sys/dev/ic: pckbc.c
Log Message:
Reduce polling of the keyboard controller status by a factor of 1000.
While on real hardware hardware a poll cycle takes time in the
microsecond order of magnitude, a "legacy-free" system which emulates
the KBC in BIOS code takes milliseconds -- I'm seeing a multi-minute
delay in booting where the KBC is probed. So poll less and use delay()
to compensate so that the total wait time stays about the same.
