Subject: Current -fixes GPU formats vs TS

Here are current figures from 1.7.9-jumbo-6-fixes branch, using GTX 570
on bull (those that pass was snipped):

The numbers 1050, 1216 and 1476 rings a bell, I believe they correspond
to certain max. lengths. Maybe the remaining problem is just in what TS
believes is the maximum length?

form=nt-opencl                    guesses:    0 unk unk : Expected

Zero is pretty definite. These needs some fixes.

Expected count(s) (1050)  [!!!FAILED!!!]

These actually look like the formats had their max lengths increased, so
maybe we should just adjust the Test Suite? If so, please give me or Jim
a notice. I really do not have time to chase information from the source
code.
