With a different card, I get:

PCI[0] bus 0 slot 1/0: unknown vendor 0x1095 product 0x0680 (RAID mass storage, 
rev 0x02)
...
nbd: registered device at major 43
sil680: 133MHz clock.

... but then it hangs here.

The first card (that failed) is a SATA/PATA PCI card, this one is an old IDE
PCI card.  I think they conform to different PCI specs.  Another difference
is that CFE knows that my old IDE card is a PCIIDE card ("PCIIDE: 1
controllers found") whereas it doesn't find a PCIIDE controller for the newer
card (I think CFE hard codes PCI devices so this is hardly surprising).
Maybe the problem is that CFE didn't properly initialize the card?
