It's ok. I was just talking to Prarit on other IRC about dynamic PAE. I
think he won't like it when he looks more at what's involved - you'll
need to rewalk all the kernel page tables on transition and lots more
ugly shit.

Not quite though from what I hear (trying to reconcile what Thorsten
said). But perhaps he was solely complaining that most people would run
PAE and thus have to type kmod-crud-PAE. I still stand by what I just
said to Prarit that I'd kill off the PAE kernel and find out who
complains about having a 32GB i686 non-x86_64 system around...but that's
just my Friday sense of humo[u]r.
Jon.
