No, sorry. bus rescan by drvctl needs a "rescan" method to be implemented
by the driver. I believe I'm the only person who implemented such methods
so far, and I didn't dare to touch the ata probing stuff because this is
known to be hairy (and the way ATAPI is handled doesn't make it easier).
I don't have any experience with ESATA -- is there any real hotplug
detection? Does it use AHCI and or SAS?
