My apology, then -- on my 6.2 system hw.acpi.thermal.user_override knob
is not present:

twinhead# sysctl -a | grep override
hw.pci.irq_override_mask: 57080
twinhead# uname -a
FreeBSD twinhead.rabbitslawn.verizon.net 6.2-STABLE FreeBSD 6.2-STABLE

root at twinhead.rabbitslawn.verizon.net:/usr/obj/usr/src/sys/TWINHEAD
i386

It does exist on my RELENG_7:
sunny:RabbitsDen>sysctl -a | grep override
hw.pci.irq_override_mask: 57080
hw.acpi.thermal.user_override: 0
sunny:RabbitsDen>uname -a
FreeBSD RabbitsDen.RabbitsLawn.verizon.net 7.0-BETA2 FreeBSD 7.0-BETA2

but OP seemed to state 6.2 above.

Sorry for the noise.
