WebGL CTS. Maybe setup a wiki page or trello or bz or whatever w/ some pointers to info about how to disable gpu blacklist (to run the cts tests in the first place) and how to run cts, and table of nv generations. I guess you don't have hw or time to test everything yourself, but this is something that distros and users can help with. The idea for wiki/trello/whatever was to help coordinate that and track open bugs for failing CTS tests.
