PCI Bus not recognizing cards properly

[sat]

Summary:
Two PCI SCSI Cards, one Ethernet PCI Ethernet card.
kernel 2.2.7-vger--> ALl the scsi cards work, the ethernet card doesn't

Any new kernel/ or any kernel that I compile--> The first scsi card doesn't
whow up.


The machine is a PowerMac 7600/132.

Cards from left to right in the box:

Adaptec 2940U2W
Farallon  Fast EtherTX 10/100
Adaptec 2940UW
--

The first SCSI card is an Adaptec 2940U2W, which is only recognized by
booting with the vmlinux.2.2.7-vger kernel from
ftp.linuxppc.org/linuxppc-pre-R5/kernels/old

(Can somebody explain how I can get the source and .config for this kernel?)

Since my boot parition is on a scsi hard drive connected to the U2W card, I
can't boot unless I use this kernel.  (Open Firmware recognizes this card
though, and is able to load the kernel off of the hard drive conected to
this card fine.)

On another note, the ethernet card is being recognized, but seems to be
disabled.  The card is a Farallon Fast EtherTX 10/100 Card, and their web
site seems to indicate that a Tulip driver should work for this card, so
I'm a bit flummoxed as to what I should do to get this card working.   I of
course would like to upgrade to a newer kernel and see if that makes the
card work, but then the scsi card refuses to work, so that nixes any
solution from that end.


Any help from any angle would be appreciated.   Any kernel patches will be
gratefully tested to fix this problem.


Thanks again.

<- Note: the PCI 13/0 just doesn't show up under newer kernels, and the
ethernet card seems to want to reassign itself to PCI 15/0.  ->
