+xserver-xorg-video-intel (2:2.9.0-1ubuntu2.2) karmic-proposed; urgency=low
+
+  * Add 102_b43_pciid_update.patch. Fixes detection of a new b43
+    chipset revision that is being shipped. Without this the drivers
+    will not attempt to load even though this chipset is the same as
+    the previous b43 ones. Backport of upstream commit 55b5fe8880.
+    (LP: #640214)
