Ran into the same problem. Installed a new SATA disk on an x86_64
system, copied/configured/booted FC3 installation, and attempted to
reconfigure grub to use the new /boot partition.  Attempting to run grub
or grub-install to update boot record results in "Segmentation fault".
The old MBR is not changed.  Not sure what kernel update may have to do
with it.  Behavior is the same for at least the last 3 kernels tried.
