hmm... thanks but no it doesn't
i have some code from the AMD papers already but it fails to compile. now that i think of it im not sure djgpp supports 64bit. ill try compiling with gcc 3.4 in gentoo.
just out of curiousity is anyone else here developing on amd64?

One assumes you're using the amd64 version of Gentoo, not the x86 version, otherwise that won't work either. It's like sticking some PowerPC or SPARC assembly language instructions into your source code -- it ain't gonna work unless you're either running in that environment or you're using a cross-compiler.
