Although unrelated to your ati install and what it may have done, I
see two possible problems when looking at your grub.cfg.
1. There isn't an "insmod lvm" within the menuentry stanza. ext2,
raid, and mdraid are insmod'd twice in the header and once in the
menuentry and lvm is inmod'd just once in the header. (This is one of
the grub2 mysteries; why multiple insmods of the same modules?). I
doubt that this is the source of the problem (the first insmod must be
enough!) but you could add "insmod lvm" within the menuentry.
2. In the uuid of the search line, what is
785366b0-d597-4e9c-9284-b6b9161236ed? One of your /dev/sX1's uuid?
Since raid and mdraid are loaded, can't you/shouldn't you use the md0
uuid above?
