When booting from cd, while you now try from hd?

Then you may edit your /etc/X11/XF86Config-4 - file.
Boot with the option '3'; yes - a single THREE without ...=3, which means runlevel 3, which is multiuser and networking without X11.
BTW: order of options doesn't play a role.
Code:
mcedit /etc/X11/XF86Config-4
look for the display-sections, and modify:
Code:
        SubSection "Display"
                Depth     32
               Modes "1024x768" "800x600" "640x480"
        EndSubSection
to
Code:
        SubSection "Display"
                Depth     32
               Modes "640x480"
        EndSubSection
for all Depths (colordepth).
