Well, it works well enough for me at the moment, but it's not complete. 
_How_ complete it will get depends on how thoroughly you want grub to 
search for possible partition maps, lvm and raid layouts, etc...

Fair enough--LVM on raid is pretty common though, well I have a few 
systems that use it at least. Of course, they all have a separate 
filesystem for /boot that is on RAID-1, so that grub-legacy can boot 
them. :)
