Yeah, sorry -- that was poorly phrased. I didn't mean that we should be
pursuing 64KiB pages because we are inappropriately beholden to our
employers -- it was more an observation that some poor bugger at some
point is going to have to deal with the issue anyway.
And since we're already _doing_ it (and mostly, we already _did_ it to
get FC6 out the door), and since it's helping us find real bugs on all
architectures, maybe we should just keep doing it. I don't recall a
single case of a program failing on a 4KiB-page kernel because it was
built on a 64KiB-page kernel, although I can certainly imagine how it
might happen.
Yes, there is the issue of (organised and documented) access to test
machines; we need to deal that with whatever the page size, and the test
machines need to match the builders.

Christ, isn't that fixed yet?
/me looks... er, did we not even assign the corresponding bug to HAL?
Or is there a separate HAL bug other than 431045?
