Dell E6400 Display Corruption

I usually run Ubuntu on my laptop since it boots so fast, but occasionally I'll need to do a lot of work in Outlook or use my IP phone so I dual boot Windows 7. I hadn't used Windows 7 on this machine in months so I thought something must be physically wrong because this started happening, but it wasn't happening in Ubuntu...

It took me forever to find this, but it turns out there is a bug with this particular Intel chipset and the Windows 7 drivers when you have VT for Direct I/O enabled in the BIOS. I must have turned this on at some point. Disabling it in the BIOS fixed the issue.
