hdparm can unregister and re-register an entire IDE channel, at
which point the channel gets re-scanned. The hdparm source
comes with an "idectl" script that makes this easy.

Don't know about individual IDE devices, though. My
understanding is, it's all or nothing--IDE registration applies
to an entire channel. Also don't know how well Linux handles
serial ATA.
