It's kind of hard to run anything over SSH if it has to be run before userspace is up. But the kernel can collect results from a modified memtest, after it chains back.

What are you saying? Linux is going to fix faulty RAM? The point with testing RAM is you *want* to see it fail; you don't want Linux to fix it.

	2) if memory only fails while something else happens (DMA to
	other piece of memory? Hard disk load glitching powre
	supply?), memtest will not see the problem.

These are not RAM faults. The very last thing you want is evidence that you've got a faulty piece of RAM when the fault is actually a hard disk glitch!
