Yes, you'll need a 32-bit Wireshark.

I was able to build a 32-bit Wireshark on a 64-bit Fedora (Core 13) 
system by:

- installing the 32-bit version of every library Wireshark needs
- running: CFLAGS=-m32 PKG_CONFIG_PATH=/usr/lib/pkgconfig ./configure
- and then building Wireshark.

The PKG_CONFIG_PATH points to where Redhat stores, for example, the 
glib-2.0.pc file for the 32-bit version of glib.

I do not know if Ubuntu supports the coexistence of 32- and 64-bit 
versions of basically everything, though.

Sure, it should be: just install a 32-bit OS and then install Wireshark 
on it.
