Framebuffer Resolution

I installed a copy of BackTrack 5 R2 (Ubuntu 10.04) to my HDD and dual-booted with Windows 7. After a bit of tweaking I set about updating the native Intel drivers because it was only allowing me to choose between 800x600 and 1024x768 resolutions and I have a widescreen laptop.

Uninstalled current drivers, added the new repository, and updated the latest Intel drivers. Start X and voila! 1366x768 resolution. Perfect...almost.

BT uses a custom framebuffer bootsplash that is hard-coded to 1024x768 resolution. When I start X server my resolution changes as it should. However, when I end my session, the resolution does not change back and I'm stuck staring at a bland framebuffer because the theme won't work at the wider resolution.

Now I realize this isn't the end of the world, but I'm wondering if there is a way to configure this so that it will return to the 1024x768 resolution when I end my X session.

Any suggestions?
