One question is whether the card gets probed when you statically compile
the driver into the kernel.
Another is, what happens when you rescan that bus? (camcontrol devlist -v
should show which SCSI bus is allocated to your driver.)
A path inquiry gets sent out when you register the bus
(xpt_bus_register()), so that's probably what you're seeing.

Yep, it'll be nice to have a Tachyon driver.
