Well, I have an Adaptec AHA-2906 SCSI card in a G3 blue/white tower at
work, so I can tell you it does work with Linux. However, you won't be
able to boot an OS from a SCSI drive hanging off said card - the 2906 does
NOT have a boot ROM on it, so OpenFirmware CAN NOT talk with the card.
You'd need a card with a boot ROM (A Mac version of one of the 2940
family or one of the newer Ultra160-based controllers, however, would work
- they actually have a boot ROM on the card).
As I said, once Linux is booted, the Linux kernel has a native driver for
the board, so Linux itself can use the card. If you could create two small
partitions on your boot drive - one for /boot (where your kernels live)
and an Apple_Bootstrap partition (for Yaboot to load from), then you could
have your root FS on the external SCSI drive, and just have Yaboot load
the kernel from the /boot partition, which would then happily mount your
root FS off the external SCSI drive.
If you are confused and would like more help trying this, contact me off
the list, and I'll see if I can help.
