I have no idea. I neither wrote the driver, nor do I have the device.
So, drop IA64?

Yes, the AMD Geode CPUs are all x86.

You need to state which members of the Geode family have this hardware.
 e.g., Is it only the Geode LX CPUs?

Well, no idea. It was not stated in the existing old help text either.

I checked the datasheets for the Geode GX, Geode LX and Geode NX and only the Geode LX has an on-chip random number generator. So this driver must be for the Geode LX only.
