PCI Bus not recognizing cards properly

[sat]

FYI, I fixed the entire problem by moving all the scsi connections to a
single Adaptec 2940U2W card.   Newer kernels ( compared to the 2.2.7-vger)
work fine in recognizing the scsi and farallon ethernet card, and
everything seems to be working fine.

Does anybody have an Adaptec 2940UW card and a 2940U2W card working
together in the same machine?

My only caveat is that the 100 Mbit ethernet card seems to be choking on
the bandwidth.   The Machine is a 7600/132.   Is this too slow to properly
handle 100Mbts?  Transfers of files via netatalk seem to be very slow, far
slower than using the built in PowerMac ethernet.

The card is using the tulip driver, so if anybody can drop me some tweaking
advice or experience, I would appreciate it.
