Have you tried a different video card? I believe the problem may be related to that, but I'm not 100% sure. You can also try this patch. Copy the patchl to the floppy disk. Remove the floppy and reboot using the Mandrake Linux 9.0 CD1 to do a CD-ROM installation. During boot, press F1 at the splash screen, then place your floppy disk that contains patch.pl in the floppy drive. At the prompt, type "patch", then follow the installation as usual.
