You could also try PAE kernel for your current system.  Open and search 
synaptic for:

    linux-image-2.6.31-14-generic-pae

if the kernel does not work you will still be able to revert to your 
previous kernel.  Read more here for Karmic package here:

    http://packages.ubuntu.com/karmic/linux-image-2.6.31-14-generic-pae

IMHO going with 64 bit would be better though, as Johnny mentioned.  The 
PAE is another option, especially if you can't install 64 bit.
