I don't think this is a good argument. The little gain of making
a rarely used library like libkvm simpler can't justify adding
overhead to the kernel.
PAE is a "bridge technology", interesting only for few systems.
Users of low-end i386 systems would be penalized, and most users
of boxes with >4G memory would gain nothing because they run
a 64-bit system anyway.
So, imho, no kernel overhead is acceptable.

best regards
Matthias
