i got back to looking at the landisk not working since 2.6.31.  linux-3.5=20
boots up with better information, so we can get further in figuring out wha=
t=20
went wrong.  for a recap, 99f95f117848088f2708b45c70be73152e78bb8a was the=
=20
last rev i could boot.

with 2.6.30.9, i see these address ranges:
Autoconfig PCI channel 0x8c3543e0
Scanning bus 00, I/O 0xfe240000:0xfe280000, Mem 0xfd000000:0xfe000000
00:00.0 Class 0200: 10ec:8139 (rev 20)
        I/O at 0xfe240000 [size=3D0x100]
        Mem at 0xfd000000 [size=3D0x100]
00:01.0 Class 0180: 1191:0009 (rev 07)
        I/O at 0xfe240100 [size=3D0x8]
        I/O at 0xfe240108 [size=3D0x4]
        I/O at 0xfe240110 [size=3D0x8]
        I/O at 0xfe240118 [size=3D0x4]
        I/O at 0xfe240120 [size=3D0x10]
00:02.0 Class 0c03: 1033:0035 (rev 43)
        Mem at 0xfd001000 [size=3D0x1000]
00:02.1 Class 0c03: 1033:0035 (rev 43)
        Mem at 0xfd002000 [size=3D0x1000]
00:02.2 Class 0c03: 1033:00e0 (rev 04)
        Mem at 0xfd003000 [size=3D0x100]

but with 3.5, i see:
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [io  0x1000-0x3fffff]
pci_bus 0000:00: root bus resource [mem 0xfd000000-0xfdffffff]

pci 0000:00:01.0: BAR 1: assigned [io  0x1420-0x1423]
pci 0000:00:01.0: BAR 3: assigned [io  0x1424-0x1427]

notice how the dma ranges are completely in the wrong region.  any quick id=
eas=20
where to fix this ? :)
