logical partition:

Can you point me to my source of misunderstanding?
Or is this a shortcoming of the grub legacy (0.97) implementation?
- If yes: Has this functionality been implemented / tested in GRUB 2 yet?
- - - - - - If yes: Is GRUB 2 to be considered as stable for production
use yet?
- - - - - - - - - - - (Unfortunately, the GRUB Homepage is a bit
contradictory in itself upon this issue ;)

Many thanks in advance!
Kind regards
