You don't really need to rescan the IDE bus. Linux doesn't use the BIOS
for disk access, it just needs it for booting (the same applies to most
modern PC operating systems). If you tell Linux to mount a device it
will just try to mount the device, and if there's nothing there or the
hardware doesn't work it will give you an error.
By the way, SCSI is different. You actually do need to rescan a SCSI bus
to pick up new devices.
