Intel Atom (ValleyView Mobile) not correctly supported by intel_extreme driver

Description

I'm triple-booting my Acer TM B115 netbook. Since most of the time I'm running Archlinux on bare metal and Haiku in VirtualBox, I didn't notice that Haiku's intel_extreme driver started to support my GPU. So, when booting hrev51502 x86_64, I was quite surprised to see a slightly scrambled Desktop - it was shifted to the bottom, showing a big black bar at the top and missing the lower part, the left part was displayed on the right, and the right part on the left:

Scrambled desktop.

The last time I booted Haiku on bare metal before I noticed the change, I was still at hrev51206 when framebuffer.accelerant was loaded (I'm booting with EFI).

listdev identifies the GPU as

device Display controller (VGA compatible controller, VGA controller) [3|0|0]
  vendor 8086: Intel Corporation
  device 0f31: Atom Processor Z36xxx/Z37xxx Series Graphics & Display

listimage | grep accel displays the used graphics driver as:

 1522 0x000000b15387d000 0x000000b153a95000     0          0 /boot/system/add-ons/accelerants/intel_extreme.accelerant
TEAM  971 (/bin/grep accel):

And Screen application uses the name "Intel Atom (ValleyView Mobile): Screenshot of Screen application under hrev51502.

I've attached the syslog file.

BTW, just noticed that framebuffer_accelerant was removed in hrev51207, since then, vesa_accelerant should be used for both EFI and BIOS systems as backup driver.

Let me know if you need further information or if I can help testing a modified version of the intel_extreme driver and accelerant.

BTW, could someone remove "Has a Patch" from the ticket description and change the component from "- General" to Drivers - Graphics - intel_extreme? Thanks.

Problem still exists in hrev52301 (x86_64). It might be a good idea to remove support for this chipset from intel_extreme for the beta.
