I was away and just got back, but looking at your forum link and your 
(badly unthreaded) posts, I just have one question.

After all these, did you go to fedora and update-grub or grub-install?

Understood the following....
o Ubuntu /boot is in separate partition, sda1, and not encrypted.
o Fedora /boot is encrypted
o You can finally boot into Ubuntu with some modifications to Fedora 
menu.lst (I am surprised, really, without the root=xxxx in kernel line 
or without chainloading). Okay, sub-question...do you want Ubuntu's grub 
to set to mbr? Then, after booting Ubuntu, why not just "sudo 
grub-install /dev/sda"?


Caveats-
o I do not have experience with Fedora, Red hat years ago is forgotten.
o I do not have experience with encyption, but understand grub2 works 
well now without hassle.


Confession-
o I reply to you as no one else did (considering I do not have 
experience with Fedora, encryption, raid or lvm)

As to your 2 questions,
o already mentioned, I am surprised it boots at all, you should need at 
least root=/dev/sda1 in it. It's okay without ro splash or quiet. Or at 
least use chainloading to the Ubuntu grub. But then, again mentioned, I 
have no experience with Fedora and the grub-legacy used may work 
differently.

o When Ubuntu kernel is upgraded, you should also amend the Fedora 
menu.lst with it.
