Grmbl, I must have missed that case when I submitted my fix last time (I
only did it in the actual DGA2 usage, not in the 'probing' code).

The actual root cause is (for me), a 'feature' in the X server that, instead
of reporting the extension as missing on remote clients, report it as being
present but then send error messages when trying to use it.
