Bug#708123: [grub-pc] grub2 (2.00-14) fails to install on RAID arrays (rescue, boot is broken)

I can reproduce the bug described in #5. I've upgraded from wheezy to
jessie and have a MB-fakeraid (RAID 0) installed via dmraid 1.0.0.rc16-5
package.
root at welanduz:~# uname -a
Linux welanduz 3.13-1-amd64 #1 SMP Debian 3.13.5-1 (2014-03-04) x86_64
GNU/Linux
root at welanduz:~# lspci | grep RAID
00:11.0 RAID bus controller: Advanced Micro Devices, Inc. [AMD/ATI]
SB7x0/SB8x0/SB9x0 SATA Controller [Non-RAID5 mode] (rev 40)
Grub used to work without errors. My fakeraid partitions where visible
in the gnome-disk tool and mounting eg. NTFS wasn't a problem. Until the
upgrade to jessie and the new grub package:
ii grub-common 2.00-22 amd64
ii grub-pc 2.00-22 amd64
ii grub-pc-bin 2.00-22 amd64
ii grub2-common 2.00-22 amd64
Booting different OSes still works but the fakeraid partitions aren't
recongnized by gnome-disk anymore although the fakeraid appears to be there:

I don't know how i would setup a VM forcing use of dmraid with
MB-fakeraids probably that's a reason for not appearing in that scenario.
