[OE-core] how to change the resolution of qemux86 machine to 320x240?

[Yi Qingliang]

Hi!

I have a s3c2442 system with 320x240 touch screen, and I want use qemux86 to 
simulate it on pc.

I googled, got "vga=xxx" in kernel arguments, but no success.
use "vga=ask" can select resolution, but no "320x240".
what's the right way?
