nvraid raid0 udev and dmraid problem

Hi,
I have problem with detect my nvraid (bios raid, fake raid).
When i boot installer from arch CD and modprobe dm_mod dmraid detect my raid array without problem.
After install when i boot from disk using grub 1.99 dmraid detect only one disk and raid array is not activated.

I think the main problem is udev. On cd is version 151 on my disk is 167.

On udev 151  when detect sda i have message

sda: p4 size xxxxxxx exceeds device capacity, limited to end of disk

on udev 167 is

sda: p4 size xxxxxxx exceeds beyond EOD, [b]truncate[/b]

And the TRUNCATE  in my opinion is the problem. Becouse  metadata of bios raid is on every each drive in array at end of the disk. When udev truncate disk the metadata is gone on  and dmraid cannot assemble array.

I try to downgrade udev on my install but i cant ... newbie in archlinux

PLEASE HELP

ps sorry form my english ;]

-------------------------

i was wrong. Problem is in libata. I try to replace it by version from cd but on cd is kernel in verson 2.6.33 and on my computer is 2.6.38, so the modules not work (modprobe -f)
