[Plug] Scsi setup problems

[Mental <mental@neverlight.com>]

Hey, I'm having a hell of a time figuring out this scsi problem. I 
upgraded warhammer to 2 (soon to be 3) seagate baracuda drives. If 
I cat /proc/scsi/aic7xxx/0 the hard drives are negotiaoting a 20m/sec
transfer rate. How do you enable 40? I enabled it in the scsi bios.

Also, in order to get the drives detected, I had to go into the scsi 
settings and change the termination from automatic to Low ON/High ON.
Whats that all about? The drives are attached to an LVD cable, and 
have unique ID's set. Weirdness. I'm not overly familiar with SCSI stuff
so I'm runing out of ideas.

All 3 drives are seagate barracuda drives. They should be UW. I have
a cheetah drive in my workstation and an adaptec 7890 controler. It
negotiates 80M/sec just fine. 

Here's the relevent messages from dmesg:
