Wow Patrick, clearly something I'm doing in size 64 has changed (and only appears on cc1.0  :o), will check.  we're going to need to fix that before moving on.

[Later:] @Patrick: when you can, please reboot & try the attached fix attempt ( for compute cap 1.0)... If OK on that card I'll be able to avoid breaking that again...

It looks like you fixed it, full loggings for completion sake:

Jason G:
Phew!  cool, thanks  ;D

Not much headroom on that chip either, but I'll be happy with that small fraction improvement on the oldest cards for now. 

Moving onto test #9 soon, will add in the FFTs, then will stream the test kernels after that, just to see what that does... Progress at last  ;D
