While it certainly makes sense to expect a performance hit for mem above 4GB
on 32 bit systems I don't see why there should be any a priori reason to
either move to 64 bit or take a performance hit for if you need, say, 2GB of
RAM. The problem is that 2.4 Linux considers HIGHMEM to be anything above
896MB.

this.
