For anyone who wants to try out this version of xterm.

You need (or at least I did) to install ttf-bitstream-vera first (which was available for me through the application manager).

The debs can be found at the following website (since one of the files is 200K bigger than this forums attachment limit):

http://andrew.olmsted.ca/maemo/osso-xterm

Next download and install the debs in the following order: libvte-common, libvte4, osso-xterm

These files should just install overtop of your currently installed files and give you no trouble. I don't know if this will conflict with the osso-software-version package, but it might since the files have a lower version than the stock files. Installing these files could in theory prevent any further upgrading of your software.
