I am currently dealing with EXACT same problem......
Best as I can tell (can't get any answers from irc) it MUST be software RAID on 2.6.x kernels.
Trying to find information on SuSE portal is not an easy task. The error message I believe is refering to this page.

If it is INDEED true, why don't they just say right at the error message, or give the exact URL.
So my question, is whether or not a doze box with supplied drivers will operate faster that my SuSE with software RAID.
I'm building this box to replace a NT4 server with same RAID (MB, SATA, & Driver) on a 100 mbit network. This new server is amd_64 asus a8n-e w/ 2 250 gig sata2 drives that will be pugged into a gigabit network solely for the purpose of providing a SAMBA share.
Will the software RAID be fast enough for SAMBA share on gigabit network with a dozed full time apps getting their data realtime from server?
I guess if it is not, then, there are 2 questions.
Is there a TRUE high perfomance hardware RAID that IS supported?
or (depending on above answer)
Would I be better of to mirror drives with rsync after hours....
I have never yet seen a motherboard with true on-board hardware RAID. I have however just setup a software RAID 5 solution using suse 10.1. Watching 'top' whilst hammering the box, gigabit Ethernet + a couple of Xen VMs I've never seen the CPU utilisation for the MD RAID Daemon exceed 1.3% of CPU resource, typically it's 0.3 to 0.7%, I can live with that. Alternatively I think the 3Ware RAID controllers are pretty well supported by Linux although most of these are 64Bit PCI and won't fit most desktop motherboards.
