Per request I downloaded the 10/24 rawhide. Graphical install proceeded without difficulty.
Because of the previous mess I took the precaution of installing grub to the boot partition instead of the MBR, and made the appropriate entry in the active menu.lst file.
Removing the "quiet" from Fedora's boot, booting seems normal until Linux announces it will try to resume from the swap partition sdc6. That's when the continuous divide errors start.
