Yesterday I decided to upgrade my home server from it's PRE_SMPNG
state to -current, but now it panics just after detecting the
aic7810 RAID controller (though unsupported, the box booted happily
on an PRE_SMPNG kernel). The 398X adapter is one of the cards that
doesn't work with AHC_ALLOW_MEMIO (as I understand it because of the
PCI-PCI bridge) so I don't know if the recent changes here has
something to do with it.
