Details:

My Grub boot screen seems stuck in 1024x768 and will not change despite my
grub.cfg asking it to use either '2540x1440' or 'auto.'

If I enter commandline mode the output of videoinfo is:

List of supported video modes:
Adapter: 'Cirrus CLOD 5446 PCI video driver':
 No info available
Adapter: 'Bochs PCI video driver':
  No info available
Adapter: 'EFI GOP driver':
 0x000 1280x1024x32 ...
 *0x001 1024x768x32 ...
 0x0003 640x480x32 ...
 0x0002 800x600x32 ...

EDID version 1.4
 Preferred mode: 2560x1440

The system is using an Intel i7-3770K with onboard video via the display port
(this is an Intel HD 4000).  The monitor is a 2650x1400 native display that
works just fine when I am booted into X at that resolution.  The problem seems
localized to the Grub boot screen.
