As Warner mentioned, I've been working on some updates to the driver recently, currently sitting in PR 50644. All the cards I have now work for me on 5.1 (must try a more recent -current soon...) However, the laptop I'm doing this on is an ancient OLDCARD-only Thinkpad 380D, so I have no idea how well (if at all) it works with NEWCARD. If anyone wants to test it, that would be great :-) Scott
