My setup (on i386, but it should be sufficiently the same):
o Comment out the 'ss*    at scsibus? target ? lun ?      # SCSI
  scanners' line in your kernel config -- I was told there were some
  issues with it, and uk* is a better match; recompile, install
  kernel and reboot -- check for the lines:
	uk0 at scsibus1 target 6 lun 0: <, Scanner, 1.80> SCSI4 6/scanner fixed
	uk0: unknown device

o Change the permissions of /dev/uk0 (or whatever your scanner gets
  attached as) so that the user who does the scanning has read and write
  permissions (one way to do it would be creating a group 'scanner',
  giving /dev/uk0 to it and making it group writeable).

o make a symbolic link from /dev/uk0 to /dev/scanner -- that's where
  sane and friends go looking first.

Another note: If you turn on the scanner after booting, you can get it
recognized by running
	scsictl /dev/scsibus0 scan any any
as root (replace scsibus0 by the bus your scanner is hanging on, if
you have more than one scsi controller card in your computer). Removal
doesn't work, though.

Hope this helps,
 Thomas
