Some of the drivers (AHCI was mentioned to me as a culprit) take a long
time to discover all the devices attached to them.  Even for ones which
are relatively quick, if you put a lot of them in a machine, it will
take a long time in aggregate.  This can be fixed by adding support for
asynchronous scsi scans, which causes the time-consuming portions of
initialisation to take place in threads.

The time-consuming portion already takes place in a thread. Do you mean multiple threads? Or, ATA's scan is in one thread, while work continues in other threads?

Patch seems sane, provided that I am educated a bit :)
