You can get an unofficial .deb or compile from source on a remaster of knoppix. I think Fabianx also made an install-on-demand-to-ramdisk script.

One way to make more space on the live CD is to remove openoffice 1.0.3 and replace it with openoffice 1.1. That save me about 30mb on the size of my iso, even having added mpalyer and its libs...
