Unable to get Intel driver working on ThinkPad T520

[Kevin Oberman]

With the new xorg installed, I decided to take the plunge and try out
the KMS drm code. I rebuilt xorg-server and the mouse, keyboard, and
vesa drivers as well as replacing intel with intel-kms with
WITH_NEW_XORG. Everything seemed to go well.

After a reboot of the patched kernel, I started X, but still got the
VESA driver. I looked at Xorg.0.log and I don't see a problem. I am
attaching the file.

I also created an xorg.conf that specified the intel driver. That led
to xorg dying with a message that no screen could be found. The log
shows:

Here is info on the graphics unit:
vgapci0 at pci0:0:2:0:     class=0x030000 card=0x21cf17aa chip=0x01268086
rev=0x09 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '2nd Generation Core Processor Family Integrated
Graphics Controller'
    class      = display
    subclass   = VGA

Any idea what I might be doing wrong?
