X is being very odd :-)

After playing with the CLI on my *really* old made-for-windows linux box, i finally abused xf86config enough to get a sembelence of a GUI running (it's, for some reason, running a 800x600 desktop on a 640x480 resolution). But now when i try to run SaX2 it comes back with and error that the kernel is not in framebuffer mode. how do i set it to framebuffer mode so i can get it working?!?!
