[PATCH] EeePC graphics

[PATCH] EeePC graphics

[-- Attachment #1: Type: text/plain, Size: 189 bytes --]

Hello!
I am playing with my old EeePC 1000px and 9front.
Here is the patch to make default mode 1024x600x32 work. Without that,
only 800x600 is supported.

aux/vga -m eeepc -l 1024x600x32

On one hand, I don't have the hardware to test -- on the other,
seems safe enough to me. Committed, thanks for the patch!
