Given the venerable age of the systems Core i3, filing a bug report with Mesa
and especially Intel wouldn't make much sense. ;)

The manpage for the currently installed driver says:


Option "AccelMethod" "string"
Select acceleration method.  There are a couple of backends available for 
accelerating  the DDX.  "UXA" (Unified Acceleration Architecture) is the mature
backend that was introduced to support the GEM driver model. It is in the
process of  being  superseded  by  "SNA"  (Sandy‐bridge's  New  Acceleration). 
Until  that  process is complete, the ability to choose which backend to use
remains for backwards compatibility.[...]


And I found the same in the manpage for the latest driver on
https://www.x.org/archive/individual/driver (xf86-video-intel-2.99.917.tar.bz2,
2014-12-21).

So I guess the options to avoid the freezes with pre-Sandybridge-CPUs are
probably limited to either use (even) older drivers or the method described in
my earlier post. The latter one works here and AFAICT comes without
performance-penalties.

So long!
