drm and i915 issue on Dell Latitude X1 ?

a curious thing... on my Dell Latitude X1 (scanpci -v output
at the end) the drm module did not recognise the video card
until i added this patch:

The board has two PCI IDs, 0x2592 (at PCI 0:2:0,
which is the one that drives the LCD screen) and 0x2792
(perhaps this is a dual-head card ?).
Apparently the drm module only looks for the latter even though it is
not the one that drives the LCD screen.

I am not sure what is the appropriate fix here, whether the
drm module  should look for all PCI IDs of the card,
or something else.

Further info below: the output of scanpci -v and the relevant
lines from /var/log/Xorg.0.log

DRM, GLX modules show up in xdpyinfo.

By the way, there doesn't appear to be an 'ident' field for
drm_pciids.h
in the binaries, though I'm on 1.2.2.3.

glxgears runs as expected (~260fps in default scale at 1024x768x32bpp). 
I tested with an application by running games/gltron, which claims 
25-40fps in 512x384 full-screen. It still seemed jerky.

[Except after an ACPI suspend/resume via zzz, in which case, it cains 
the CPU on resume and only achieves 60fps-150fps, and acpi_video cannot 
attach, and gltron is jerky/doesn't work properly.]
