But wait! I was stupid... Of course it's a different register....

Not only does this actually *work* on the AXP 8X00 for the ISP, but
converting the aic7770 driver to use memory mapping makes the PCI
bridge problems I was having with the Adaptec 3985 go away... which
means I can turn the PCI-PCI bridge stuff back on. Yes- Alan, that
should make you dance in the streets..

I'll send you the diffs before I go. The isp can just convert
over to using memory mapping. dwlpx_pci gets a slight change (and
finally gets the #if 0/#endif pairs used sensibly). The AIC driver
is a bit more of a change, but I'll hold off on sending you that
one since Justin thinks he'll working on stuff by Monday or so
(actually, the question now arises, see below, about why only
one of the two or so SCSI busses attached...)

In either case, what with the patch I sent you yesterday about ISP1
and this, I think we're moving up from first baby cries right smartly...
