Card, yes.  Bus, no.

It's an Adaptec 39160 which is Ultra 160 SCSI with 
dual channels.  /dev/sda through /dev/sdf (I think) are on
Channel A.  The rest are on channel B.

I will work on serial output, but maybe not until tomorrow since
I don't think I have a null modem here at school.

Both partitions from /dev/sda mounted, and none from the other 
devices (regardless of where they are on the SCSI bus).  So, this
could be the common feature.
