kernel error: unichrome card + dri

hi all

I'm trying to get my Unichrome video card working (P4M890).

01:00.0 VGA compatible controller: VIA Technologies, Inc. Unknown device
3343 (rev 02) (prog-if 00 [VGA])
        Subsystem: ASRock Incorporation Unknown device 3343
        Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 233
        Memory at a0000000 (32-bit, prefetchable) [size=512M]
        Memory at fd000000 (32-bit, non-prefetchable) [size=16M]
        Expansion ROM at fe9f0000 [disabled] [size=64K]
        Capabilities: [60] Power Management version 2
        Capabilities: [70] AGP version 3.0


All I see after starting X is "black screen" :(

Last 2 lines from Xorg.0.log:
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)

I see kernel errors in my /var/log/messages:
