If I mount the fs with -o inode64, can I mount it again later say under
knoppix 32bit without any options, will the FS still mount? The 64-bit
rescue cd/dvds--I have had problems with to say the least.

Not yet. I'll hopefully get a patch for it into 2.6.28.

Actually it *will* at least mount, won't it? But that's dangerous. I
don't think xfs sets any kind of superblock flag saying "I contain
inodes past 2^32, don't mount on 32-bit boxes" does it?

Right. It will mount, but what happens with inodes past 2^32 is
undefined. You might be lucky - you might not....
Cheers,
