I got it working! Thanks to the *great* support of phcoder from the 
grub2 community!

He developed a patch that allows the user a sane way to override 
auto-detection mechanisms by supplying right device.map. It should get 
merged to bzr in the next couple of days :) (it is not yet ideally 
coded, but works :)

--> Basically allowing me to use /dev/md126 (the imsm Volume) as a grub 
device, even though grub can't assemble it --> hence to use the int13 
OROM assembled version of the raid-0 :)

If you want to give it a try:
     # http://www.gnu.org/software/grub/grub-download.en.html
     bzr branch http://bzr.savannah.gnu.org/r/grub/trunk/grub
     # Apply this patch: http://pastebin.com/raw.php?i=tgfqp9Hn
     # e.g. download it to file "phcoder.patch"
     # and run cat phcoder.patch|patch -p 0 in the "grub" directory that 
you received by the bzr command

     # I think without any parameters it should be fine:
     ./configure
     make
     # this command triggered for me that /boot/grub got populated:
     # for me /dev/mdYOURVOLUME was /dev/md126 (the imsm Volume)
     ./grub-probe /dev/mdYOURVOLUME
     # make sure that /boot/grub/device.map contains:
	(hd0) /dev/mdYOURVOLUME
     ./grub-probe /dev/mdYOURVOLUME -v
     ./grub-probe -t partmap /boot -v
     # until know we changed NOTHING...
     # ... so if you can also do this:
     ./grub-install /dev/mdYOURVOLUME
     reboot

Hope this helps you as well.


Best,

Knuth
