You say it doesn't work.  That's pretty vague.  If it fails in some way, what
is the mode of the failure?  (See also
http://en.wikipedia.org/wiki/Failure_causes#Component_failure)

Are the member locations incorrect (query through the API)?  Is the row-major /
column-major orientation of the matrices incorrect (query through the API)?  Is
the generated code reading the wrong locations?  Does it crash in the driver? 
Does your computer catch on fire?

Without any information about how it actually fails, it's pretty much
impossible to fix.

When I check it now, it should have everything.  The other question: does this
work on older Mesa?  Say... a 10.2 stable release?

> Can't I just wait for new build in PPA?

You can... at some point there will probably be a patch for you to test, and
that won't be in PPA.  You can probably wait to worry about it until such a
patch exists.
