All VIA x86-compatible processors since the C3 (introduced 2003?) have included a hardware random number generator based on quantum effects; it produces millions of random bits each second, and is accessible with a non-privileged instruction. AFAIK, their opcode choice is unused by either AMD or Intel, so those companies could implement similar functionality (an infinitesimal bit of silicon) and we would have a standard solution at least across the x86 architecture going forward.
