When you say it does't work, what do you mean? - Does it crash, stay in SVGA
mode or stay in text mode?

I have had a few problems with GFX_AUTODETECT on some hardware, have you
tried specify an actual mode, I find that GFX_VESA2L works with most cards
in 640 x 480 mode.

Without more details of what "doesn't work" really means, I can't really
offer any more advice!
