nonhot-swap disks and linux on ml350

I have a few nonhot-swap non compaq disks in my ml350g2.

They are seagate u320 drives, with an adaptec u320 cable with terminator.

They get recognized during the boot phase, as ASYNC, but not as hard disks.

Linux recognizes the hot-swap drives OK, but does not assign a /dev device to the non-hotswap drives.

they drives are visible to the scsi and adaptec modules, but sd_mod does not assign a device.
