does FreeBSD {can,will,patch exist} supports using huge pages? i mean 2M pages on AMD64 and 2/4M pages on i386

i don't mean any automatics, just enough will be to be able to map a big chunk of RAM to an app with such pages, or even more (better) to make FreeBSD use only part of memory for itself, and leaving everything else as /dev/something that can be mmap'ped (and locked) to program this way.

i need freebsd just for running one program needing about 1280 megs of data space (+1-2 meg of code stacks etc. can be normally mapped). everything else is just using less than 1% of power.

with 1536MB AMD64 machine it would be nice for FreeBSD to boot seeing 256 megs for itself and allowing 1280 megs to be mapped&locked to just one program.

thank you very much
