fgrx stopped booting of xservers

I installed fglrx and fglrx-updates. I got following messages from xinit:
(WW) fglrx: No matching Device section for instance (BusID PCI:0@1:0:1) found
(EE)No devices detected
Fatal server error:
no screens found

And lspci give this:
01:00.0 VGA compatible controller

And section Devie from xorg.conf file:
Section "Device"
              Identifier "aticonfig-Device[0]-0"
              Driver "fglrx"
              BusID "PCI:1:0:0"
EndSection
I don´t know what can I do?

it is probably difficult with udev not fglrx or intel . there is no device file in /dev?!
