In most ports of FreeBSD parts to Linux that I've seen, the preferred solution 
has to been to bring the entire FreeBSD queue.h with you rather than relying 
on the native Linux queue.h.  This is what we do for OpenBSM, for example; 
this also helps out when you get to Mac OS X, Solaris, etc, where all the 
queue.h's continue to vary in subtle ways.  This depends a fair amount on a 
lack of header pollution in the OS's own include files, of course...
