what distro are you using?
if you aren't very familiar with Linux, i would suggest picking up Novel's OpenSUSE 64 bit - works wonderful on AMD64 and Intel 64 out of the box, it's a bit large, but comes with 32 and 64 bit libs and everything else you could possibly want out of Linux system. Ubuntu is a nice desktop release, but is much more stripped down than SUSE.
btw, if you are using 32bit linux (which u can on 64 bit cpu) you shouldn't have to do anything to get BMAX working. However, i strongly recommend using 64bit OS on 64 bit system, specially AMD64 which is a native 64 bit CPU with also runs 32bit code natively, without having to emulate some crap like Intel does.
also, AMD64 differs from IA64 implementation, like 3DNOW and SSE3, but new releases like SUSE should be just x86_64 and have support for both.
