CPAN Testers already does this for testing CPAN modules and Perl on a vast range of OSes (and hardware) - http://wiki.cpantesters.org/

Organising this for Linux would be harder given a bootable system is required, but it could be done.

This works so well because by default CPAN client does tests when installing modules, and send those results to CPANtesters. So it is very easy to become CPANtesters contributors.

Perhaps a request at install / upgrade time to perform regression benchmarks of one's system before first run would be a good idea for Linux testers project?

That's a good idea - there are already some projects that do functional testing of hardware on new systems, what's missing is the feedback into central test results repository. Though it would need to be a distro-independent test approach so it can be used with the latest kernels as well as distros.
