Default LP#74179 -- support for i386 machines with >3GB RAM

We are seeing increasing complaints that users are failing to be able
to use all their RAM when installing more than 3GB of RAM when running
the i386 kernels. This is due to the RAM being placed at greater than
4GB physical addresses; it is common to have RAM from 0-3GB and at 5GB
physical when installing only 4GB. In order to access this RAM we need
to enable PAE, but this is a non-trivial change for the common user.
The server flavour does have PAE enabled, but is not optimised for the
desktop and users are unwilling to use it. They should be running 64bit
kernels but that is probabally not quite as seamless as it should be yet.

Therefore I am proposing we create a new i386 only flavour generic64g
which is identicle to the generic flavour except that it enables PAE and
options that that requires.

Following this email is a patch implementing this for Jaunty.
