That did it! Out of curiosity, where did you get the port and irq values?
Are those common for Alphas, or did I miss something that I should have
read?

It seems to be completely working. I disklabeled, newfsed, and mounted an
IDE drive with no logged errors. On a related note, while I didn't expect
this implementation to be as fast as the ATA/100 channels on my i386
motherboard, I didn't really appreciate how glacially slow it would turn out
to be:
root@gopher:/root# bonnie++ -u 0:0 -d /usr/local2/
Using uid:0, gid:0.

I may end up getting some SCSI drives off eBay yet for the sheer sake of
being able to outperform the DAT drive in my backup server.
