As it's in the buffer:
kern.timecounter.choice = TSC(q=-100, f=3314703750 Hz)
clockinterrupt(q=0, f=100 Hz) hpet0(q=2000, f=14318180 Hz)
ACPI-Safe(q=900, f=3579545 Hz) lapic(q=-100, f=200933289 Hz)
i8254(q=100, f=1193182 Hz) dummy(q=-1000000, f=1000000 Hz)
kern.timecounter.hardware = hpet0
kern.timecounter.timestepwarnings = 0

First thing, I've noticed my current kernel is better .56 (the
previous was .55), currently it only pauses at the 'root
filesystem:ffs' portion, it's not paused at the bit after the CPU
detection for several boots.
FYI It pauses here:
Disabling acpicpu had no effect.
Disabling hpet had no effect either. (I was fishing. ;) )
Booting with ACPI disabled (boot -2) works fine every time.
Some dmesgs in case they're any use:
One last thing, I have seen a screenfull of error messages a couple of
times just before it reboots, after the disc syncing messages,
capturing these proves quite an excercise in timing. :)

focus, the subject is a fickle mistress and kept rebooting!! ;) )
