I did, but no predictability tests, only FIPS 140-2 or so. It checked out pretty well but someone claimed that the RNG was predictable because it was probably only used for some of the coding for wireless. I don't know how to test this hypothesis as I don't know enough about QAM and whatever codings are used there (nor do I know where you'd need (pseudo-)random numbers)
