>Description:
	The current ahc driver fails to use the ultra scsi mode for
	scsi devices > id 7.
>How-To-Repeat:

Jumper a ultra scsi drive at id 8:

ahc0 at pci0 dev 10 function 0
ahc0: interrupting at irq 9
ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs
scsibus0 at ahc0 channel 0: 16 targets
ahc0: target 8 using 16Bit transfers
ahc0: target 8 synchronous at 10.0MHz, offset = 0x8
sd0 at scsibus0 targ 8 lun 0: <IBM, DCAS-34330W, S65A> SCSI2 0/direct fixed
sd0: 4134MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sect x 8467200 sectors

and then jumper it at an id <7:

ahc0 at pci0 dev 10 function 0
ahc0: interrupting at irq 9
ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs
scsibus0 at ahc0 channel 0: 16 targets
ahc0: target 0 using 16Bit transfers
ahc0: target 0 synchronous at 20.0MHz, offset = 0x8
sd0 at scsibus0 targ 0 lun 0: <IBM, DCAS-34330W, S65A> SCSI2 0/direct fixed
sd0: 4134MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sect x 8467200 sectors
