For the sake of completeness (and people searching the archives) Centos3.5 has the drivers I need.
Drivers for just the ATA/SATA channel support? Or the FRAID disk organization?
I've seen people think the ATA/SATA driver is the FRAID support, when the FRAID is in addition to the ATA/SATA channel support.
I dont' know - how do I tell? I fired up a 3.5 install, it saw the disks, and I installed.
Creating a 100Meg files seems pretty good: time dd if=/dev/zero of=/var/tmp/blah bs=1024 count=100000 100000+0 records in 100000+0 records out

Thanks to all who suggested alternate methods for CentOS versions that do not.
In kernel 2.6, the LVM2-DM (Device Mapper) can do a lot. It can read the FRAID vendors disk organization, and LVM2-MD can handle provide the software RAID logic (without the vendor's proprietary, 3rd party code)
It's also _very_broken_ too.
Furthermore, vendors change disk organization/logic continuously between models.
Lastly, I've also not seen FRAID-5 supported yet either.
