Got this on my machine as well:
[   11.538880] etnaviv-gpu 38000000.gpu: model: GC7000, revision: 6204
[   11.566889] etnaviv-gpu 38008000.gpu: model: GC520, revision: 5341
[   11.575804] [drm] Initialized etnaviv 1.3.0 20151214 for etnaviv on minor 0

I've yet to test some GPU load though.

Best regards,
Alexander
