Does not work.

Still failing. Only thing that works is either:
$ROOTCMD /usr/sbin/grub-install --no-floppy --modules="biosdisk part_msdos ext2 lvm raid" "(hd0)"
$ROOTCMD update-grub
or 
$ROOTCMD /usr/sbin/grub-install --no-floppy --modules="biosdisk part_msdos ext2 lvm raid" /dev/sda
$ROOTCMD update-grub

Anything speaks against "(hd0)"? This would work for most of the
cases. For RAID1 users an example like this might be enough:
$ROOTCMD /usr/sbin/grub-install --no-floppy --modules="biosdisk part_msdos ext2 lvm raid" "(hd0)"
$ROOTCMD /usr/sbin/grub-install --no-floppy --modules="biosdisk part_msdos ext2 lvm raid" "(hd1)"
$ROOTCMD update-grub

I am using 1.98 from Ubuntu/Lucid.
