It has the same name with 2.6.26.3 and with 2.6.27-rc7-something with
fastboot merged. So why would this be a regression? The different name
(scsi-...) happended with a vanilla 2.6.27-rc7.

Initially, my intention was to find a unique name for the hard disk,
that stays even if the disk is changed from Firewire to USB. However,
this doesn't seem to be possible with a default udev.
