To be honest, I thought the data from the TCO random generator was funneled in 
already. That's what the "intel-rng" module does.

Current kernel built with:
CONFIG_HW_RANDOM=y
CONFIG_HW_RANDOM_TIMERIOMEM=m
CONFIG_HW_RANDOM_INTEL=m
CONFIG_HW_RANDOM_AMD=m
CONFIG_HW_RANDOM_GEODE=m
CONFIG_HW_RANDOM_VIA=m
CONFIG_HW_RANDOM_VIRTIO=m

If your CPU has the hardware the module should be loaded, but you can check with 
"lsmod | grep rng" to be sure, or load manually to test. Also virtio_rng might 
be useful. You might have to load by hand to test, then config to load by 
default if you want.
