Unfortunately you don't: what you've done is confirmed that this bug 
("mesa breaks beignet") is fixed, what I wanted was a test for the 
opposite problem ("does beignet break mesa?"), which requires AMD hardware.

That's this bug, so this confirms it is now fixed.  (The fix is included 
in 1.0.1-1, currently in the NEW queue.)

That's expected: 0.8 only supports Ivy Bridge (ix-3xxx), your hardware 
needs the newer version (which is only in experimental because of the 
release freeze).

> With mesa forced I get:[...]

That's also expected: mesa-opencl-icd isn't supposed to work on Intel 
hardware, the bug was that its being installed broke beignet as well.
