I hope it will be based on benchmarks - I see no reason to drop any
flavours if there maybe a significant performance benefit for a
significant part of our userbase[1]. I want as many people to run the
official kernel as possible and not to regress to the woody days
where any clueful admin built/ran their own.

In lieu of convincing benchmarks, the default answer should be to
*not* drop flavours. Without numbers, users are going to believe
(rightfully or not) that running Debian's kernel reduces the power
they get from their hardware. That factor is worth the slower build
times and extra disk space.

fwiw, a coworker is looking into the availability of a benchmark that
should be good for comparing pae/non-pae.

[1] whatever that means.
