1: %dmesg | grep -i hpet
ACPI HPET table warning: Sequence is non-zero (2)
acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on
acpi0 acpi_hpet0: HPET never increments, disabling
device_attach: acpi_hpet0 attach returned 6

2: Yes, I have to run it every time for it to work. Not once my CPU
load is detected after reboot, unless running ntpd.

3: Yes, I had problems with mounts in the future and whatnot. I don't
remember what I used where, but on Linux I used to remove a
file, /var/lib/hwclock/adjtime and run ntpd - for the things to get
in line.

4: In the debugger it prints: $1 = 0, so I suppose yeah, it is set to
zero.

Laterz!
