This is correct: Intel dropped the RNG after the first few releases of their ICH chipset (which is now up to ICH5). Not much Dell can do about it. Intel's RNG was slow anyway, compared to the AMG and now VIA RNGs, so you didn't want it anyway :) I really like VIA's "xstore", which is an RNG implemented via a CPU instruction. That way you don't need a kernel driver at all, really.
