GPL-miscibility (or the lack thereof) isn't a stumbling block which  
would affect the adoption of such code into a BSD project.  The main  
BSD flavors: FreeBSD, NetBSD, OpenBSD, etc will readily accept 4- 
clause BSD code, as well as Apache, ISC, MIT, Zlib/PNG licenses...but  
the 2-clause BSD seems to be generally preferred.

They'll also accept GPL'ed code if it works better than alternatives  
under a permissive license, at least into userland and optional/not- 
built-by-default kernel modules.
