Googling "twiki mediawiki" gives several bodgy scripts others have written to make the move. So you may have to hack together some of those. But at least you can put the results up on mediawiki.org for those following you :-)
Actually, I've started a page:
http://mediawiki.org/wiki/Twiki
Not that I can add meaningful content to it myself ;-)
