I compiled and have this running, seems OK.
Kqemu does not compile against these sources, however (not that I would use it
with the kernel but it should compile!).
They have their own linux-firmware-nonfree and linux-libc-dev. Are these safe
to use with non-patched 2.6.33 or with 2.6.32 kernels? It would seem dangerous
to have rt-specific versions of such generic packages.
