:It worked fine until I started xorg -- then time started going fast. I
:gained an hour in approx five real minutes.
The video BIOS is messing with the 8254. It may be worth a shot
to try to use timer 1 instead of timer 2.
Try putting this in /boot/loader.conf:
hw.i8254.walltimer=1
If this doesn't work, or the machine crashes or fails to operate
reasonably, you can recover by dropping into the loader (option 6 from
the menu) and unsetting the variable before booting, then boot
normally and remove the line.
I am assuming you are booting without ACPI? Usually the ACPI timer
is used if you boot with ACPI and this problem doesn't occur. If ACPI
doesn't work for you it may still be possible to boot with ACPI just
to get at the timer, but with most of the features disabled. 'man acpi'
tells you how to disable certain features.
