Status of linux compatibility

[david]

I was wondering what the status of linux compatibility is when running 
freebsd in 64bit. My concerns are with precompiled binaries that can't 
be recompiled. In my particular case, I am interested in running game 
servers. The main problem I can forsee is when running a 32bit linux 
binary on the 64bit system. Will this work at all and if so what issues 
can I expect. As soon as I get the amd64 machine I'll do my own tesing, 
but in the mean time, what do you guys have to say?
