First off make sure you've enabled Ultra speeds in the Adaptec's BIOS
(ctrl-a at boot time when the message comes up), secondly make sure you're
using ultra devices.

Probing for devices on PCI bus 0:
chip0: <Intel 82439> rev 0x03 on pci0.0.0
chip1: <Intel 82371SB PCI to ISA bridge> rev 0x01 on pci0.7.0
ahc0: <Adaptec aic7880 Ultra SCSI host adapter> rev 0x00 int a irq 11 on pci0.11.0
ahc0: aic7880 Wide Channel, SCSI Id=2, 16 SCBs
              ^^^^^^^^^^^^ This should probably be changed to identify
				ultra channels.  The aic7880 and ahc2940UW
				are Ultra Wide controllers.
scbus0 at ahc0 bus 0
sd1 at scbus0 target 0 lun 0
sd1: <QUANTUM FIREBALL_TM3200S 300N> type 0 fixed SCSI 2
sd1: Direct-Access 3067MB (6281856 512 byte sectors)
^^^ This is a Ultra-Narrow drive.  Speeds above 10mhz (I think) are Ultra
	speeds.  The speed is shown if you boot -v
sd0 at scbus0 target 1 lun 0
sd0: <QUANTUM LIGHTNING 730S 241E> type 0 fixed SCSI 2
sd0: Direct-Access 699MB (1431760 512 byte sectors)
cd0 at scbus0 target 4 lun 0
cd0: <MATSHITA CD-ROM CR-506 8S05> type 5 removable SCSI 2
cd0: CD-ROM can't get the size

If you boot -v you'll see something like this for Ultra devices:

ahc0: target 0 synchronous at 20.0MHz, offset = 0xf
