I was interested in the data being provided for /dev/random; that seems
like the most important interface to me. But, exposing all of the
devices using consistent names does seem like a useful idea at some
level.

I like the notion of using all of them in turn; if one of them turns out
to be broken, you're still stirring in data from the others. After all,
the quality metric is provided by the device, we aren't doing any
analysis on the data to determine it independently.
