error loading xorg with framebuffer enabled

[Vincenzo Ampolo]

Hi to all
i wanted to enable framebuffer on my pc so i went to menu.lst of grub
and set vga=792 properly.
At reboot the framebuffer is set but xorg fails to execute.
Does anybody know anythig? Is it a common error or i'm just to stupid to
solve this problem? 

thanks a lot

ps: this stuff is need for a under developing bootsplash that works in
usermode. It is started by rc scripts.
