I have X1053A FSBE/S (sun part # 501-2015) cards, one of which went into an
SS2. Attached to a disk that will do Fast SCSI-2 (e.g. a DEC DSP3160S), it
can sustain 6.5 MB/s just dd'ing. However, the FSBE/S is handled by the
"esp" (and "le" for the Ethernet) driver, rather than the "isp" driver.

	another data point,
