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.

We find there is another device id set for B43 chipset. After adding the device id 4E90/4E92 beside 4E40/4E42, the machine works fine with the same modification in xserver-xorg-video-intel.
