[Openchrome-users] trying to get DRM working on a 1106:3344 (unichrome Pro)

[dave denney]

I'm working on a Gentoo Linux system running 2.6.16-gentoo-r7 with
a VIA EPIA EN15000 motherboard, which has a VIA CN700 North Bridge
and a VIA8237R South Bridge.  I was able to get everything working
for our application, except DRM.

The lspci for the VGA shows:

The non-verbose output of lspci:

I get an error in Xorg and no Direct Rendering enabled:

I selected this board because I thought the Unichrome Pro video
was well supported, but apparently there are several different
versions?  Is there any way to get this working? I tried searching
the openchrome-users email list, but found nothing... I'v had
no trouble with DRM on our older VIA systems that arent 'Pro'.

Thanks in advance for any help!
