This sounds awesome - and saves me the trouble of doing it!!
I started using the old polls module for a site the other day and decided it needed a re-write but unfortunately I'm totally swamped at the moment. I got as far as re-writing the 2 snippets to output more reasonable markup, adding HTML+CSS bar-chart results and re-doing the CSS.
This is what the modified poll looks like, if you use my CSS:

The rounded corners are provided by jQuery and this plugin:
