I've been researching my next laptop purchase, and whether it will run
Linux, and completely accidentally stumbled upon an alarming issue that
people need to be more aware about.

Apparently (and if my understanding is correct), HP/Compaq disables
dual-channel memory access in Socket 939 motherboards, making CPU <-> RAM
communication slower, and overall performance less than what people would
expect when buying a system with the outward characteristics of what they
think they are getting.
