There may have been an error creating the initial ramdisk for your new 
kernels when they were installed. See if mkinitrd reports any problems:

# mv /boot/initrd-2.6.10-1.741_FC3.img /boot/initrd-2.6.10-1.741_FC3.old
# mkinitrd -v /boot/initrd-2.6.10-1.741_FC3.img 2.6.10-1.741_FC3

If that looks to work OK, try booting into the 2.6.10-1.741_FC3 kernel
