>Description:

* the highlights:

- vendor 0x1283 product 0x8888 (miscellaneous bridge, revision 0x03) at pci0 dev 12 function 0 not configured

that's a "PCI to ISA Bridge with SMB" from ITE.  datasheets are
available at http://www.iteusa.com/product_info/PC/Brief-IT8888_2.asp .
could be split to a separate PR, since it's not part of the GX2 geode.

- pciide0 at pci0 dev 15 function 2
- pciide0: vendor 0x100b product 0x002d (rev. 0x00)
- pciide0: bus-master DMA support present, but unused (no driver support)
- pciide0: primary channel wired to compatibility mode
- pciide0: primary channel ignored (other hardware responding at addresses)
- pciide0: secondary channel wired to compatibility mode
- pciide0: secondary channel ignored (not responding; disabled or no drives?)

it works, but is obviously slow and CPU-heavy.

- vendor 0x100b product 0x002e (audio multimedia) at pci0 dev 15 function 3 not configured

AC97 glue.
