i965g driver fails to create pipe_screen and falls back to software rendering.
It tries to create it with radeon chip id instead of intel chip id. 'startx'
outputs the following errors:

i965_drm_winsys_screen_create
brw_screen_create: unknown pci id 0x68e0, cannot create screen
dri_init_screen_helper: failed to create pipe_screen


Intel graphic controller is on cpu, core i5-460M arrandale, PCI:0:2:0, 0x0046.
radeon graphic controller is Mobility Radeon HD 5000 Series, PCI:1:0:0, 0x68e0.
Mesa and DRI drivers were built from git
bd5b7a6f7113da38a2c1f07a4a71e9993666a567 (master from today).
