I'm using an AMD Athlon 64 processor in my PC and I have long been dissapointed by that fact that a large number of applications in the FreeBSD ports collection works in i386 only. Initially, I planned to emulate an x86 PC so that I can compile them, but I later realized that doing 32-bit on a 64-bit arch is uhm... a bit stupid.
But anyway, I'll recompile the kernel today and see if I can run i386 Linux binaries on FreeBSD. One of the applications that I hope to run is Zend Studio. Zend Studio is (apparently) a Java app, and it requires libXaw, libXt, and other libraries that conflicts with xorg-libraries. Dunno yet how to proceed. I also hope that I'll be able to run Open Office.
I'll be following the instructions published at http://people.freebsd.org/~tjr/linux32.html.
