It appears as though VIA 64XX might be able to do hotplug, at least
according to the Linux SATA pages - at least they don't claim "does not
support for lack of information from PHY" or something to that extent
which they do for other controllers.



I am not sure if someone has actually tried to implement SATA hotplug
for Linux on VIA chips though, so I'm deliberately writing "it appears
... it might", not "it does support...".

Perhaps you can ask the Linux SATA guys where to look or get the needed
