Description hychen 2010-09-16 02:49:00 UTC
System environment: 
-- chipset:Intel  i810 B43 VGA board
-- system architecture: 32-bit
-- xf86-video-intel: 2.9.0
-- xserver: 7.4+3
-- mesa: 7.6.0
-- libdrm:2.4.14
-- kernel: 2.6.31-60
-- Linux distribution: Ubuntu GNU/Linux Karmic
-- Display connector: VGA

Reproducing steps:

Excepted result:

    Intel video driver is loaded successful and X wroks. 

Actually result:

   Itel's X driver can'tbe detected and used correctly and X runs on low resolution with VESA driver.

Additional info:

   lspci -n reports the device id for agp/video is 2e90/2e92 which is not in the list for xserver-intel driver, the device id in the driver is 2e40/2e42. 

  The attached patch added 2e90/2e92 in the detect function and It is basically works fine to me.
