i've submitted a fileserver kernel driver for the marvell
sata-ii 88sx[56]0xx set of cards. this revision adds hotplugging
support and a workarounds for various drive firmware
compatability issues. (thanks to sam hopkins.)

we have two 88sx60xx cards in Coraid's new main file server.
hotplugging allows us to make a copy of the f device
while the fileserver serves files. (between dumps, of course.)
the copying code has not been submitted as it has not been
well-tested yet.

unfortunately i have not yet had time to port this driver back to
the cpu kernel. if anyone is interested in doing this (perhaps
as a summer of code project), i would be happy to help and/or
mentor.
