nothing on this address (with 3.4 kernel).

on 2.6.32 I see:
0a30-0a3f : pnp 00:07
0b00-0b7f : pnp 00:0c
0ca2-0ca2 : ipmi_si
0ca3-0ca3 : ipmi_si
0cf8-0cff : PCI conf1
1180-119f : 0000:00:1f.3
  1180-119f : pnp 00:0e
d000-dfff : PCI Bus 0000:06
  d000-d01f : 0000:06:00.0

on 3.4-rc4:
  0a30-0a3f : pnp 00:07
  0b00-0b7f : pnp 00:0c
0cf8-0cff : PCI conf1
0d00-ffff : PCI Bus 0000:00
  1180-119f : 0000:00:1f.3
    1180-119f : pnp 00:0e
  c000-cfff : PCI Bus 0000:06
    c000-c01f : 0000:06:00.0

I'll try comparing both kernels' dmesg output in more detail to see
if there's some difference that might be important..
