just as an addendum; there are two things I can think of that aren't on your
list:
1. make sure the jumpers are set to different settings on the drives
2. check that the BIOS is set to detect SCSI
I have Mandrake Linux 7.0 (2.2.14) installed with the Adaptec 2940U2W with 2
IBM U2W drives. I installed it on an third IDE drive. the installer hung on
trying to detect the card or load the driver the first couple of times but I
did get it to go after I changed the jumpers and the BIOS settings.
also
the 2940U2W has it's own BIOS that you can drop into, it has utilities to
check the bus and drives.
