Nice to see that someone took over this task.
This should enable booting from an mirrored md device holding an lvm root 
partition (Raid 1). 

Question: Did anyone check wether this is possible from an RAID 5 arranged 
software raid?

Summary:  [PATCH] full Linux-LVM support

Original Submission:  Attached is a diff against grub (sorry, not latest 
release, I hope this is not a serious problem) which adds full Linux-LVM 
support to grub. It even supports loading of stage2 from stage1.5 (+4k) and any 
combination of Volume Groups and Logical Volumes. Snapshot volumes are 
untested, but should work. LVs are accessed like this:
"root <system:boot>", i.e. <vgname:lvname> - the corresponding block devices 
are sorted out by the LVM code. Autocompletion works, it is documented in 
grub.texi, selectable via configure, the ChangeLog was updated - I tried to 
make it as complete as possible.
One point remains: I copied linalloc_* from gunzip.c and adjusted the memory 
address, it seems to work but please someone else look at it to make sure it is 
correct.
(If my estimations are correct, it won't conflict with gunzip.c, but I don't 
know what lies below that memory area. 256GB total LV space uses ~512k memory 
currently)
