[Intel-gfx] Intel 965 and Custom Resolutions

[Lucas]

Hi All,
 
Pardon me if this has been discussed before but I sure as heck can't find the answer.  Perhaps my googling skills aren't good enough.
 
Anyway, I have an AOpen DE 965-HG mini PC that has - surprise! - Intel 965 graphics.  It has an HDMI-out port which I have connected to my 42" plasma Panasonic TV.  The TV is a little old (circa 2005) so it apparently reports the wrong EDID information.   It also needs to be adjusted for overscan.  When I try to run Linux (any kind, but currently Ubuntu 10.04) X server it picks up the wrong resolution.  With a different computer (NVidia graphics chip) I was able to disable EDID checking to set my custom Modeline.  I can't seem to be able to do that with the Intel driver.  It ignores my custom resolution and gives me the first of two incorrect resolutions.
 
Could somebody please guide me in how to disable EDID so that I can view my TV in all its HD glory?
 
 
Thanks!
 
Lucas
