Hmm, I don't know. We usually prefix print statements in the driver
with KERN_* things, so I don't know why they're not being logged.

It uses whatever you have set in Adaptec BIOS for sync rate setting for
that device. Note that this is the maximum synchronous data transfer rate,
the device can negotiate lower transfer rates, but the driver limits the
rate to what is set in BIOS. My 1533 at home, I think, negotiates at
a rate off 8.0 or 10.0 MHz. Check you're BIOS settings and see if they're
set to 5.0 MHz.
