We too are waiting for SMicro to release the Serverworks boards with
**functioning** RAID on them.
For example we are using their 1020P-T server, but for now have to use a
3rd party card, such as the 3Ware 9550 to get this working.
As I understand it the problem is something in the SWorks/Broadcom chip.
As far as "RAID" goes, from what I understand the SWorks is still a
"FRAID" device, so I think your idea about using mdadm or similar
software RAID makes good sense for a RAID1 scenario.
About the only drawback that counts (to some) would be the lack of disk
