Details:

grub-mkconfig search for vmlinuz images in / and /boot directories to make the
entries in grub.cfg . 

When a vmlinuz kernel image is on / lvm partition, GRUB does not verify the
partition where the kernel image is on, and sets the root of /boot partition.

For example, an entry like:

 insmod part_msdos
 insmod ext2
 set root='(hd0,msdos1)'
 search --no-floppy --fs-uuid --set=root 8d488250-7be3-4db5-990d-5b7affdabb6f
 echo    'Loading Linux 2.6.38.4 ...'
 linux   /vmlinuz-2.6.38.4

Should be like:

 insmod lvm
 insmod part_msdos
 insmod ext2
 set root='(vgentoo-root)'
 search --no-floppy --fs-uuid --set=root 6a7250b9-e143-467b-95ba-5a05ec693335
 echo    'Loading Linux 2.6.38.4 ...'
 linux   /vmlinuz-2.6.38.4

Where module lvm should be inserted, and root var and partition UUID should be
changed.
