The RAM wasn't bad enough to fail post, but it did occasionally flip bits on the data registers of one of the chips. Not all RAM test software can catch that, but the Dell diagnostic software did. Of course the same thing can happen if your BIOS has overly aggressive RAM timings set. Since your problems occurred regardless of the kernel, it would certainly imply a hardware problem.
