the patch didn't apply cleanly to the installed package (tried on both
/usr/lib/grub/update-grub_lib and /usr/lib/grub/i386-pc/update-grub_lib,
which appear to be identical files)... 

so i manually applied the changes, and it appeared to work... although
there are now three "set root=" entries in grub.conf ... two that point
to (hd0,2), the location of the /boot partition, and the first still
points to (vg-root)... so that sounds a little quirky.

the good news is, now it actually boots without manual intervention.

here's the generated grub.cfg:
