Which version of XFree86 are you using?  3.x is unsupported now, so you
should probably be running 4.x, but I'm not sure what Mandrake includes
by default.  Anyways, if you're running 4.x and you can get booted
sans-gui to a command line, you can run "XFree86 -configure" and it
should detect everything you need and store the configuration in
"XF86Config.new" in the current directory.  Then it tells you to run
"XFree86 -xf86config XF86Config.new" to test it out, and if it works,
you just copy the config file to it's permanent home, probably
"/etc/X11/XF86Config".  You may also need to edit the file to tell X
which monitor is on which side, add any custom options, etc.  Quite
painless, and it is known to work with dual head configurations (i.e.
mine! =)  If only my video driver would get that stupid bug fixed so I
can use the second display!!! =P)
