You disable APIC for Linux, but you didn't mention disabling it for FreeBSD.

Type this at the boot prompt followed by 'boot':
set hint.apic.0.disabled=1

If that works, comment out the apic line in your kernel config file and 
rebuild.  Alternatively, you may just put the above line in 

If that still doesn't work, try safe mode from the boot loader and 
report back.

As far as I am aware, OpenBSD does not have ACPI support.  FreeBSD 
should behave more like OpenBSD in safe mode, because safe mode turns 
off ACPI support.

Hope something in the above helps,
