I'm doing this on one box here, works just fine.  The only common 
partition is /boot, which is /dev/hda1.

I'm also doing that, but its also giving me problems because the BDI 
installs ext3 isn't comfortable with the FC3's version of ext3, so 
when I go to boot the BDI partition, its drops me to a shell to fsck 
the partition (But e2fsck can't check it claiming I need a newer 
version than 1.35 which AFAIK is current), but advises me that a 
ctl-d will continue the boot, which it then does without any further 
problems.  I can boot FC3, and then the e2fsck (version 1.35 also) 
checks it just fine.

If someone can fill me in on howto alleviate that, I'd appreciate it.
