I have a 6081 (Marvell Technology Group Ltd. MV88SX6081 8-port SATA II
PCI-X Controller (rev 09)), it works fine under 2.6.15-rc5.  No hotplug,
and a few wierd problems here and there.

I'm getting ~55 MB/s/disk off each of 4 disks.  220 MB/s total read.
It slows way down when you start writing to them too, of course.
