5.3 on Compaq AP400 hangs on reboot.

Hello FreeBSD users!

I've installed FreeBSD 5.3 on two-cpu Compaq 'Professional Desktop AP400'
and have got a problem: When i reboot the mashine, it hangs instead of 
resetting the system. (that was reported in kern/27834 back with 4.3-STABLE,
but in my case there is a new interesting fact)

I use non-smp GENERIC kernel [dmesg/mptable below]

The kernel just prints "Rebooting...", screen goes blank, nothing happens until
i manually reset the mashine.

I tried ACPI, but it complains about APIC, with:

"ACPI disabled by blacklist.  Contact your BIOS vendor."
(from sys/dev/acpica/acpi.c acpi_Startup returning AE_ERROR)

called by:
MADT: ACPI Startup failed with
(the above)
Try disabling either ACPI or apic support.
  panic("Using MADT but ACPI doesn't work");

(from sys/i386/acpica/madt.c madt_setup_io())

I disabled APIC with hints.apic.0.disabled="1" and indeed system started
without any problems [attached dmesg is from that boot], but that didn't fix
anything - system still didn't restart after reboot. Apart from that, i read 
that this disables smp, so it isn't a solution anyway.

I also disabled acpi leaving apic; again, without results.

I thought that there is nothing i could do except installing linux back 
[there was a linux system there before, the person using it said he had no 
problem with rebooting] but when the ACPI panic happes (the one listed above)
and the user is prompted to press any key [or wait 15 secs]
system prints Rebooting... and really restarts the machine the way i want!

I searched for 'Rebooting' code in the kernel. found sys/kern/kern_shutdown.c
shutdown_reset which calles cpu_reset(), then, checked what shutdown(1)/reboot(1)
do and found they call the same func...
so what happens in cpu_reset() what is different at panic and normal shutdown
is still a mystery to me, but may be a hint for someone knowing the subject.

Hints? Ideas? Pointers?
I'm not very good at ACPI; seems a huge topic from 'layers and levels' one 
can apply to debugging it ;)
I'm also not very familiar with compaq's hardware; I'll try to google out if a
some bios upgrade is possible (?).

Best regards,
m.
