According to a message Martin Grässlin sent to the KDE packagers mailing
list (sorry, no archive, the list is not public), this is a new
requirement for 4.7: at least Mesa 7.10 is required. BTW, the Mesa we
have in ports seems to be 7.4.4, not 7.6.1.

Some references I can point to:

When I contacted Martin at the time of his announcement, he said this
verification was to ensure all the drivers used KMS (and their
development experience only went back as far as Mesa 7.7; 7.4.4 is old
enough for KWin bug reports with it to be ignored) and thus didn't break.
