Terminal Sizing on Startup

First can I thanks for Matchbox, I use it on small Thinkpad 240 and it 
works a treat. It means I don't have to be reaching for the mouse every 
minute and is nice and fast too.

I have a small problem in that when I startup a new terminal 
rxvt/xterm/etc they don't seem to get the correct window size so curses 
programs get confused (vi,less,lynx,top). This does not seem to happen 
all the time with rxvt, just sometimes. xterm always fails to resize 
correctly. As a workaround I have the following lines in my ~/.bashrc

     if [ "$DISPLAY" ]; then
         eval `resize`
     fi

Which works but seems a bit of an evil hack.
