Ahh, a Compaq! They don't care much for conformance to the
PCI spec and caused me lots of trouble in the past (trying
to get them probed correctly :( )

This is one of Compaq's chip sets. They designed them for
use in their systems, exclusively. No detailed information
seems to be available about them.

An AMD PCInet/32 lance compatible Ethernet chip. Supported
as device "lnc1" under -current.

Yes, this is in fact a nice little 53c810 as supported by the
NCR driver :)

Antother Compaq specific chip, a PCI to EISA bridge according
to the class code.

Didn't it say in the first line this was a config type 2 chip set ?
Well, you see how much you can trust it on that: There is no device
to be found, if you believed that claim ...
