Some of the drivers (AHCI was mentioned to me as a culprit) take a long

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 :)
