Other possible ways are:

No, in my case I really don't think it is a solution. It is rented
dedicated servers, so I can't add
hardware, and don't want have to compile anything (except the kernel).
Look into EGD, like the poster recommended. All my rented dedicated
servers have unused audio devices on them. Google for "audio entropy
daemon" for software that will collect entropy for you, from an open mic
circuit or similar "noise" sources.
Similarly, you could potentially get entropy from an unused TV/video
port on a video card.
You can even collect entropy from one machine, hopefully with a hardware
RNG of some sort, and send it to another machine.
