Yes, but use 2.6.34, something is screwy with 2.6.35.
I have two 3ware cards (9650SEs) (4port/16port) in my DP55KG.
02:00.0 RAID bus controller: 3ware Inc 9650SE SATA-II RAID PCIe (rev 01)
03:00.0 RAID bus controller: 3ware Inc 9650SE SATA-II RAID PCIe (rev 01)
Thanks for the information and advice. I'll just stay with kernel 2.6.34 then , cause that's also what I'm currently using with the RAID controller and which is also currently the stable (and thus the recommended) kernel for Gentoo.
