In addition, I get the following:

# /sbin/grub-install /dev/sda
/dev/root does not have any corresponding BIOS drive.
# /sbin/grub-install /dev/sda1
/dev/root does not have any corresponding BIOS drive.
# /sbin/grub-install /dev/sda2
/dev/root does not have any corresponding BIOS drive.
#

Mysteriously, /dev/sda is now the device with the highest priority in the BIOS.
