My whitebox Pentium 4 system has the 810 RNG, and it works. I'm not
sure which series motherboard it is; it's the one that uses cheap
commodity SDRAM, not Rambus or DDR memory.

Linux also supports the Intel 810 hardware RNG. Debian provides a
"rngd" daemon that reads the hardware RNG and shovels the bits into
/dev/random. I have it running on all my machines that support it.
