  To work around such problems (not a real fix), that's what the
ISAPNP_ALLOC_INTR_MASK is for. You can define it in your kernel
config with

	options ISAPNP_ALLOC_INTR_MASK=0xfc00

  (or whatever, I materialized 0xfc00 out of thin air (or rather
from one of my kernel configs)), it being a bit mask of which
interrupts you want to be available for pnp.
