Thanks for the answer, and good to know that you see the problem.

But, well. Both LILO and old GRUB support this configuration and it's
a valid configuration as far as the tables themselves are concerned.
If GRUB2 cannot support this, I consider that a regression. I know
LILO a bit, but not old GRUB. Cannot GRUB2 handle this in whatever way
GRUB does/did?
