I'll give this a try.  But a generic question.  Does the kernel depend
upon u-boot to initialize the PCI configuration?

And, I know this is a u-boot specific question, but will u-boot ignore
any PCI device it doesn't know about?  Thus I have to enable a
specific device in the u-boot configuration for u-boot to recognize it
(and from there, have the kernel recognize it)?

Not that I'm aware of.  I suppose the EEPROM to read in the
configuration/MAC address?  But I wouldn't think an option ROM would
be present.

Don't have any other non-x86 systems to try out.  We have an
MPC8349E-mITX board, but the PCI slot doesn't detect anything at all
(not even our 82540EM based board).  And this card doesn't work there
either.
