I'm thinking that I have some kind of strange hardware issue (like
there's some magic flag on my
  motherboard to tell it to deal properly with >4096M of memory).

I got a kernel abrt as well--"Bad page state in process swapper". 

I have a P5QL-PRO motherboard, and there seems to be some issues with
installing more than 2 memory modules in it, if they're "double sided". 
Weird stuff.
