Cleaned up xserver-xorg-video-intel patch to more closely match what
actually went upstream in this commit

http://cgit.freedesktop.org/xorg/driver/xf86-video-
intel/commit/?id=55b5fe888002258dd863d41977bfbfcf1a922179

** Description changed:

  I have a machine with Intel B43 chipset but can not using X, looks like
  intel-agp and i915 module is not loaded.
+ 
+ --- SRU JUSTIFICATION NOTES ---
+ 
+ IMPACT: A new revision of the B43 chipset has been released and the
+ corresponding drivers were not updated to recognize them until recently
+ due to the rarity, but machines are now in the wild that contain them.
+ Without this change the drivers will recognize these devices at all and
+ fail to load.
+ 
+ RESOLUTION: Adding the pci id's to the corresponding drivers, letting
+ them know they are B43 chipset devices that it already knows how to work
+ with.
+ 
+ TEST CASE: 
+ 1) Boot any ubuntu release on a device containing this chipset, which can be verified with lspci -v and seeing if 8086:2E90 or 8086:2E92 is listed. 
+ 2) Verify that i915/intel-agp are not listed in lsmod, and xserver-xorg-video-intel is the driver in use in /var/log/Xorg.0.log
+ 3) Update packages
+ 4) Reboot and verify i915 and intel-agp are listed in lsmod, and intel is the driver in use in /var/log/Xorg.0.log
+ 
+ REGRESSION POTENTIAL: Extremely low, no new code paths are added for
+ these specific devices. The changes only add the new device to the
+ corresponding drivers and they are functionally no different than the
+ previous B43 devices supported already. No new code paths are added or
+ changed to make these work.
