Bug#568975: ([squeeze/lenny][i386][2010-02-04] grub-installer fails, system unbootable)

The options for resolving it (so lenny-via-squeeze works) seem to be:
- add a debconf configuration item to specify the metadata version
I started a patch but I have absolutely no idea what I'm doing.
The attached is just an attempt to clarify what I am suggesting.
Cheers
Vince
