I tried to force use the NEHALEM or the BARCELONA driver on a PILEDRIVER
AMD box and while it fixes the original test failure in isolve it
causes this other
scipy test to fail:

======================================================================
FAIL: test_nanmedian_all_axis (test_stats.TestNanFunc)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/scipy/stats/tests/test_stats.py",

  File "/usr/local/lib/python2.7/site-packages/numpy/testing/utils.py",
line 375, in assert_equal
    raise AssertionError(msg)
AssertionError:
