When I first got my Ultra 5, I had a devalias called scsidisk, pointing to
/pci@1f,0/pci@1/scsi@1/disk@0,0. I then did a setenv boot-device scsidisk:a.

After upgrading the firmware on the U5 to the latest, that devailas stopped
working (it wasn't changed at all, I deleted it and restored it manually,
but it still didn't work) so I just did:
setenv boot-device /pci@1f,0/pci@1/scsi@1/disk@0,0:a
and it boots just fine from the scsi disk.

(I'm using an Adaptec AHA-2940UW-OFW)
