I had a similar issue with usedcars.com. We had several hundred thousand URLs that were redirecting from parameter driven URLs, to clean hierarchical URLs with a huge initiative to clean them all up in a few months. It took well over a year and still didn't see them getting recognized.

I blogged the process - but the part about what I did to speed it up:

I grabbed one of my many impulsive purchased domains and quickly set up hosting and an old school html site that consisted of one page. I then exported all of the links on the Google "site:" search through a Firefox plugin called SEOquake that exports the results into a csv file. It's not the prettiest, and there was a lot of work still needed to get to just the URLs, but it was the best solution I could find (note: if any SEO reading this knows of an easier way to do this - please add to the comments for prosperity). I then parsed out the parameters in the URLs in a separate document and used those as the anchor text for each URL. Finally, using excel I then concatenated the URLs and parameters (that were now anchor text) into an html href string.
Then copying and pasting the "string" column into the html code, the page looked like:
The page wasn't the prettiest, and it had thousands of links (the above is just an example) so it was bad all around, but the point was to get those links crawled by Google.

Of course every SEO knows that you can't just build a website and expect it to immediately get crawled - right?

So I set it up in Google Webmaster Tools and submitted the page to the the index:
I even got more fancy to ensure Google would see the page and crawl all of those old URLs and +1'd it on Google.

Did it work?

I checked the URLs this evening to see how many Google is seeing and the number has dropped from 550,000 to now only 175.

I took the domain off of the server, and now have it parked elsewhere (back where it belongs) and removed the webmaster tools account. All traces of it ever existing are now gone, and the small moment of my attempt to get those URLs removed has passed.

It's very black hat - and could potentially get you in trouble if not approached carefully. But - it worked...
