r600: fix my pessimism about PIPE_TRANSFER_x flags
as the culprit. Rebasing to latest mesa git (master) with this commit reverted works as expected.

--- Comment #2 from Francis Whittle FJ.Whittle@gmail.com 2010-11-15 23:58:49 PST --- The conditions for this failure appear to be related to sync uploads only (with or without readbacks is, at a guess, irrelevant). At any rate, commenting out the test to use a staged upload in this instance cause the missing text(ures) to reappear.
I'm suspicious that at the end of the big if( use_staging_upload ) block there's a call to r600_copy_to_staging_texture() in the case of PIPE_TRANSFER_READ but apparently no equivalent call for PIPE_TRANSFER_WRITE.
