You can get it to work just using XFdrake, although you may find you want to edit the file that generates.
8 bit color (this may be where you're hitting problems)
vga adapter, I believe
set the screen to be an 800x600 generic LCD

If you check the page in my sig it has links to a number of sites that have XFree86 setup files too.
