Not sure where you can find them on the internet, but Mike has said that they are planning on releasing a Meteora song book which will have tabs.
^ What Bryan said. If you don't feel like waiting, though, you can check out MxTabs. They have a system where tabs are given a number of stars based on accuracy so I think it's the best source for now.
or try tabcrawler.com It's not official tab, but i think you could use it. they just had some meteroa tab in recently...
I know I'm usually an ogre about bumping old threads, but I thought this was useful: In this month's issue of Guitar World Magazine (with Metallica on the cover) they have the tabs for "Faint" along with an exclusive lesson with Brad Delson. Pages 119-123. I didn't think it was very newsworthy.
