Currently I'm running OpenSuse 11.1 ...

I would like to try 64bit Linux in a multiboot configuration, while
still keeping my 32bit installation. I would make another LVM partition
and share /boot, /home and swap. I could also run various other Linux
distributions (Debian, Ubuntu and Gentoo are on my list).

I think I won't have a lot of troble seting this up, but there is one
thing that worries me a bit: the /boot partition with the kernels and
the grub config. 1 GiB is room enough for a lot of different kernels,
but I'm worried that different Linux distributions have different ways
of "automagically" configuring grub.

What are the pitfalls that I should watch out for?

I get around automagic disruption by starting with a DFSee CD, then a Knoppix
CD, before any OS CD or DVD. With DFSee & Knoppix, I completely partition,
and install Knoppix's Grub on the first primary. Only then do I install an
OS. On my most recent installs, that was 11.0. I mount the real boot
partition (hd0,0) on /disks/boot, leaving OS /boot as a part of each
configured /, and manually configure menu.lst on (hd0,0) to either chainload
to the installed OS's Grub, or directly load its kernel and initrd from its
installed location, or copy from its installed location to (hd0,0) to boot
them. You can see from https://bugzilla.novell.com/show_bug.cgi?id=463033
that had I not first installed Grub how and where I did that I probably
wouldn't be booting anything at all.
http://fm.no-ip.com/tmp/Linux/big31L03.txt shows the partitioning I did to
support shared swap, home and others, and separate / partitions for 11.0,
11.1 and Factory.
