I think the issue is that we basically spam every new bug that comes in with
a request for upstream testing. We assume that if you are technical enough
to file a bug you can install a kernel. And if you don't do the testing we
won't look at your bug.

The main problem I have with the use of Live CDs is that to test a kernel we
ask that you download a 700+ MB image. This seems like a lot to ask.

Something like a meta package which would let people just download and install
the current mainline kernel would be a lower barrier.
