Overspeed, hypertuning/autostrategy/.. and similair in unix/os x

How is it with all those features, do they work even when the driver is used in linux/bsd/os x/solaris/… or does it require some special drivers or applications? I guess there are non for OS X since Apple normally just put whatever drives they feel for anyway, what about the open oses?

Not sure about others, as actually I was looking for current alternative for Autostrategy. But Autostrategy work on hardware level on my Plextor px-716a and can only be disabled or enabled through QPXtool.
Wonder if from time you did the post you can share some info about alternatives for AS which would work well on Linux?
