The main issue in the past has simply been that it wasn't part of
the original PC architecture, so things like "looking at mouse
movements" needed to be done at first until it was added to modern
hardware.

 
The trouble with building in a purported random-number source is: how can
you be sure you can trust it?

That's the justification the designer of the circuit I linked to
stated for why they decided to use a separate circuit made from
discrete components. USB devices using similar circuits can also be
purchased for the same reason. Anyway, you don't need a quantum
computer to do it.

Intel added random-number generation instructions to the x86 architecture;
but how can be we sure they work as they're advertised?

How can you be sure anything works as advertised? There's always
the risk of backdoors in the Intel Management Engine enabling all
sorts of possible attacks. That designer likes FPGA-based CPUs for
this reason, although there's still a small risk that the FPGAs
could be maliciously designed to specifically sabotage that
approach too.
