Yep. We don't use any smarts to make sure text doesn't get clipped
off the bottom. Raise the bottom of your subplot by adjusting the
"bottom" of the subplot params
figure.subplot.bottom : 0.1 # the bottom of the subplots of the figure
You can either adjust the rc param, or use the subplots_adjust command
See examples ganged_plots.py and subplots_adjust.py

It probably is possible. Does TeX not use an italicized \Omega in
