[PATCH 0/2] Add device id for Intel B43 chipset

[PATCH 0/2] Add device id for Intel B43 chipset

[Ike Panhc]

There is another device id for Intel B43 chip. Since there is already an id
sets for B43 in intel-agp and i915. We tried to modify the kernel and
xserver-xorg-video-intel and they work fine on 8086:2E90/2E92 chipsets. I
believe this id sets is valid[1], and another patches has been sent to bug
tracking system of freedesktop[2].

Since this is a blind try, please review the patches and if there is no more
modification needed, please consider apply them.
