P35 doesn't support PCIe RAID card?

[CetusLi]

My Dell perc 5/i SAS RAID card cannot work with the ASUS P5K Deluxe.
The system cannot boot with the 5/i in each of two PCIe x16 slot.
My friend has the same issue on his new GIGABYTE P35-DS4.

Since the 5/i card used to work well with our GIGABYTE P965-DS4 & ASUS P5B-Plus, I think it should be the P35 chipset that cannot support the PCIe RAID card.

Is there anyone else has the same issue?
Can anyone recommend a mainboard for my Perc 5/i?

Thanks a lot!

I just read a review on the Abit IP35 Pro (p35 chipset) which says that the second pci-e slot does support RAID cards. The page is here. It would be odd to remove popular features on newer boards i would think.
