You have RAID1 but I have RAID5 which I'm installing Linux on it.

Also the only raid I used with Linux before was mdadm - it supported mirror too. Actually if I just wanted use raid1 I wouldn't buy nothing since Linux can set it up anyway. You had that system since 10.3 but this's the first time I put Linux in this system.
So you have 3 disks?
Yep, but only 2 in my RAID1

Having never tried RAID5 before, I didn't know a recompile would be necessary. But, I do agree with your basic premise that dmraid works great and openSuSE should fully get behind it and support it. They have been making improvements on properly handling dmraid arrays on install and making grub behave properly with them.
Just a reminder that the basic Linux approach to software raid is to use mdraid (software raid) if you can. If that cannot satisfy your needs, then move to dmraid (fake raid). Personally, I am seriously considering using mdraid in a project soon, but I don't envision myself ever using dmraid. I guess you never know so I won't rule it out.
