Call for testers: PAE for 4.x

[Luoqi Chen]

Hi, everyone,

I've ported Jake Burkholder's PAE support from -current to the 4.x branch.
This has been scheduled to go into the coming 4.9 release. You can get the
most recent set of patch files from http://people.freebsd.org/~luoqi/pae-4.
If you are interested and have a machine with over 4GB memory, please give
it a try. You may also try it just for fun, even if you don't have 4GB of
memory. Please direct any questions or problem reports to luoqi at freebsd.org.

Thanks
-lq
