Try adding to the boot command line:

	BusLogic=NoProbe

Note that this info came from the kernel source tree's file:n

	Documentation/scsi/Buslogic.txt

Note also that this probably doesn't solve your real problem: that
that controller's driver doesn't appear to work on Alpha in these 2.6
kernels... :-(

Good luck.
