There is no 1400x1050 listed, the maximum is 1280x1024. I'd be happy to use 
that, but I can't get framebuffer to work at all. All I get is 80x25 VESA 
console text mode.

I tried building an initrd that explicitly includes intelfb, but that doesn't 
work either. I can manually load intelfb later, but of course that doesn't 
give me /dev/fb0.

Bummer. Any ideas?
