Hi!

After update to 3.15-rc2, only top 20% of screen works on X.

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset
Integrated Graphics Controller (rev 03)

00:02.1 Display controller: Intel Corporation 4 Series Chipset
Integrated Graphics Controller (rev 03)
	   Subsystem: Intel Corporation Device d614
	   Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
	   ParErr- Stepping- SERR- FastB2B- DisINTx-
	   Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast
	   >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	   Latency: 0
	   Region 0: Memory at d0400000 (64-bit, non-prefetchable)
	   [size=1M]
	   Capabilities: <access denied>

This worked before. I believe it worked in 3.14. It definitely works
in 3.11-rc2.
