Chromium Text Corruption + UXA Resolution Combination Issue

I'm stuck in a catch 22 situation here so I'm hoping someone's seen this before and knows how to resolve it.

One of the machines in question for reference: Intel Core2 Duo CPU, Intel G45 GPU, 2 monitors: 1 connected via DP -> DVI 1080p, 1 connected via VGA 1440x900.

Basically a few machines running Intel GPUs are getting graphical corruption in Chromium. The fix for this is apparently to use UXA rather than SNA acceleration in the Xorg driver (or drop the Intel driver and use the Modesetting driver). But if I do this, it creates a new problem entirely...

If I switch to UXA or Modesetting, then the DVI monitor attached to the machine will no-longer display at the correct resolution anymore, it gets stuck at 1280x1024 resolution. Trying to force it via xrandr to the right resolution gives me an XrandR "BadMatch" error and trying to use a lower res results in "Configure crtc 1 failed".

In short: SNA = Text corruption. UXA/Modesetting = wrong resolution on primary monitor.

EDIT: Here is the xrandr -vv output and xorg.log for the different configurations:
Good (SNA) - http://www.hastebin.com/gofihuxigu.scala
Bad (UXA) - http://www.hastebin.com/deqibajoqe.scala
