I think this may be wrong.  My Fujitsu M2952Q ultra wide drive works
perfectly in ultra wide mode at ID=0.  It was set to ID=15 when it
arrived but I just removed the address four jumpers to set it to ID=0.

This is what I get at boot-up (OK, I know it's not FreeBSD!), confirming
that it's operating on ID=0 at 20.0 MHz (ultra) with 16-bit (wide)
transfers:

| scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 3.4/3.2/3.1
| scsi : 1 host.
| scsi0: Scanning channel A for devices.
| scsi0: Received MSG_WDTR, Target 0, channel A needwdtr(0xffff).
| scsi0: Target 0, channel A, using 16 bit transfers.
| scsi0: Target 0, channel A, now synchronous at 20.0MHz, offset 8.
|   Vendor: FUJITSU   Model: M2952Q-512        Rev: 0124
|   Type:   Direct-Access                      ANSI SCSI revision: 02
| Detected scsi disk sda at scsi0, channel 0, id 0, lun 0
| scsi : detected 1 SCSI disk total.
| SCSI device sda: hdwr sector= 512 bytes. Sectors= 4693462 [2291 MB] [2.3 GB]

I would be surprised if the M2915Q behaved in a different way, unless 
there's something up with the driver for the NCR825.
