There has been a number of studies (http://www.2uo.de/myths-about-urandom ; I don't agree with everything but interesting reading anyway) showing that entropy from Linux random is not better than from urandom (once urandom has been properly seeded). For this reason, I patched my rndlinux.c GnuPG source code file to always use urandom. Makes key generation instantaneous. When a software is stupid, I don't want to install additional stupid software or comply with stupid instructions; I simply patch it.
