Dear Release Team,
I'd like to upload a new version of Blender to stable/wheezy.
Blender package in wheezy is 2.63a-1 at the moment and doesn't include a
patch that would avoid an "illegal hardware instruction" failure related
to SSE2 extensions present in newer CPUs, as reported in #599680.
This way, however, every user using a non-SSE2 CPU (e.g., AMD Athlon)
won't be able to run Blender in their wheezy boxes.
That same patch has been applied on packages >= 2.66-1 and finally it
has been dropped in latest upstream Blender release 2.71 because there
was found a better (and more elegant) solution to the problem.
I already prepared an update on wheezy package with that patch applied
and it was tested to work fine.
Attached, you'll find this famous patch that should fix the issue.
Thanks for considering.

Subject: fix_illegal_hardware_instruction_due_to_SSE2
This makes sure it builds compatible binaries also on
machines which have sse/sse2. Fixes the SIGILL bug.
Checks for DEB_HOST_ARCH_CPU!=i386 before tests are attempted.
Will try to use SSE/SSE2 on all other architectures.
Generated Code will still need MMX support to run.
