piglit@ is for ... piglit. The issue you have isn't with piglit but
rather with the driver. Use either mesa-dev@ or dri-devel@ for that.
The bug tracker link you found is the proper place to file a bug.

While I am in no way connected to the AMD team, I can pretty much
guarantee someone will ask you what a W600 card is, so include lspci
-nn output, and your radeonsi_dri.so doesn't include any debug
symbols, making it harder to see what's going on.

Graphics development pace tends to be quick (which is a polite way of
saying that the drivers suck in various ways but are being actively
improved), so testing with the latest and greatest is definitely
encouraged. Different teams provide different levels of support for
various "old" things, not sure where AMD is at exactly in that regard.

Cheers,
