Grub2 config file for (rather) complex disk layout

[GoofyX]

Hi,

I have two disks that deploy the layout as shown in the attached image. Up to the point before the installation of Grub2 I used a initramfs image that mounted the root fs. Now, Grub2 is installed. From the feature list of version 2, I understand that Grub now supports reading softRaid and lvm groups, so my guess is that the initramfs image is now obsolete.

What changes do I have to make to grub.cfg (for Grub2), so that I will unmerge Grub legacy once and for all?
