Large memory system

Hi,

I've jumped the gun a little bit and recommended a Professor buy 4GB
of RAM on a Xeon machine to run Linux on and he did. After he got it
I read the large memory howto which states that the max memory size
for Linux 2.2.x is 2GB physical/2GB virtual. The memory size seems to
limited by the 32bit nature of the x86 architecture. The Xeon seems
to have a 36bit memory addressing mode. Can Linux be easily expanded
to use the 36bit addressing?

Thanks for any info on the subject.
