Personally, I put all the disks in JBOD mode, but I never had these
disks connected to anything but my highpoint cards. Perhaps I should
tell you what my setup's like:

* In the system I've put 3 Highpoint RocketRaid 2300 cards.
* Two of the cards each have 4 Hitachi 750GB disks
* Each disk is put into JBOD mode in the 'Raid' Bios of the 2300
* On the drives I have 2 partitions, one 200MB partition and a partition
spanning the rest of the 750GB
* Both partitions are linux softraid
* /dev/md0 is a mirror of all 8 disks and serves as /boot (200MB)
* /dev/md1 contains an LVM volume that houses my other paritions (4.7TB)

Right now with 2.6.23.9 + patched sata_mv the softraid seems to come up
just fine but I pvscan is unable to locate the pv located on md1.

I'll try and make a bootable USB stick with my patched 2.6.23.9 and see
what the results are then.
