--- Comment #1 from Marek Olšák <maraeo at gmail.com> ---
RGTC1 texturing uses only 4 bits of precision in R500, which can cause some
piglit failures. If you run the test, you'll see how the precision affects the
filtered texture. If it's not completely wrong, let's just say this is a
hardware limitation.
