I just tried, grub2 1.96+20080704-2 -- I can't even complete installing it (I 
selected the recommended chain-load):

This is the contents of /boot/grub/device.map:
   anan7:/boot/grub# cat device.map
   (hd0)   /dev/hde
   (hd1)   /dev/hdg
   (hd2)   /dev/hdh



Also, either grub2 and/or grub2-pc did not purge cleanly; it left a big mess 
of files in /boot/grub/ after both were purged, which I had to manually pick 
through and delete those:
