For me, the solution was simply compiling the latest intel code from  
the git tree, and it worked perfectly (my monitor's connected via  
DVI, by the way). The friendly folks at the Gentoo mailing lists (I  
went there first with this problem) suggested me using a custom  
modeline for my monitor which, I dunno, might do something. I guess  
I'm not being much help, but I wish you the best luck in solving this!
