panic if isapnp enabled

Hi! all,


I forgot to issue this patch...

I enabled isapnp for my kernel.  It kernel panics in
sys/dev/isa/isadma.c
::_isa_dmainit().  This reason was called match/attach of
pnpbus from
config_found_ia() for "cpu" in
prep/mainbus.c::mainbus_attach().
# Sorry I'm beginning to forgot...  X-<

I apologize if already fixed.  

Thanks,

No, I've never tried isapnp since writing pnpbus.  Good
catch, I'll try to get
that committed as soon as I get a chance to test on my
7043.
