note that there's still a problem with XFree which will "see"  those
BARs and, according to the log posted by Sven, shoke. Sven, can you
try "hiding" the host bridge completely from the config ops and see
if that helps with XFree ? That's not a very good solution though,
we'll have to do something different about it. Now if only XFree
stopped mucking with the PCI bus...

Is this a problem with overlapping PCI resources again (thought that was
fixed in 2.4 anyway)? Resolving the overlap helped there. What does XFree
do, simply disable resources?

There should be no overlap.... Let me check the log ...

(II) Host-to-PCI bridge:
(II) Bus 16: bridge is at (0:0:0), (-1,16,0), BCTRL: 0x0008 (VGA_EN is
set)
(II) Bus 16 I/O range:
        [0] -1  0       0x00000000 - 0x0000ffff (0x10000) IX[B]
(II) Bus 16 non-prefetchable memory range:
        [0] -1  0       0x00000000 - 0xffffffff (0x0) MX[B]
(II) Bus 16 prefetchable memory range:
        [0] -1  0       0x00000000 - 0xffffffff (0x0) MX[B]

The problem is on the host bridge BARs again. I don't know what they
are supposed to do, you need to look at the bridge spec, but you
definitely need to hide them some way...
