Any real-world examples?
Even OpenOffice runs as 64bit since months.
The only which I remember rumors are "grub". But being a bootloader,
that probably doesn't hurt much.
Fact is that I run pure 64bit Linux since months on my home desktop
(though I'm not the typical desktop user;-).

Yes, x86_64 has more registers than i386.

Some browsers (konqueror, firefox as far as I've been told) allow to run
32bit plugins from the 64bit version. Since the flash-plugin and others
is not really important for me, I don't really care.

Or install 32bit libs and run a 32bit browser/application on the x86_64

Yes, but that implies "Vista" there and God knows how compatible (even
to pre-Vista Windoze) the result will be.
