It's not so much that I favor ARM, just that there seems to be a huge variety of low-power (CPU and energy) systems out there based on the various levels of ARM architecture. Routers, development boards, smartphones, etc. all seem to run on ARM-licensed designs. If there's a similar quantity of x86-based low-power systems I'm not aware of it even in passing. That doesn't mean it doesn't exist, but it probably does mean that x86-based systems of the sort aren't widely internet-connected devices which means that an assembler-based CGI CMS is probably not really relevant for them. Edit: and I should add that by "really minimal" I'm not talking the true low-end of embedded microcontrollers at the Arduino level or below, I'm just talking about network-connectable devices with power consumption measured in single-digit watts.
