Trying to get scsi working

My BusLogic card is detected, but I don't seem to be able to load the module. modprobe gives:- FATAL: Error inserting BusLogic (/lib/modules/2.6.4-54.5-smp/kernel/drivers/scsi/BusLogic.ko): No such device The file mentioned does exist at the given location, so why can't I load it? Thanks, -Richard
