Ok, I started something:

https://github.com/pavelmachek/missy

I try to test -rc1 and final versions on thinkpads X60 and X220. (I'd
like to do testing of even -next from time to time.) I do have T40p
and test maybe every other version on that one. I test Nokia N900
quite often (including next), and plan to test N9/N950 too.

Of course, more "exotic" hardware would be welcome. I did have linux
on sun4/330, unfortunately I don't think I have access to that any
more.

Best regards,
									Pavel
