Does sound sorta-like VM thrashing.
Could it be hardware based _bank-switching_ on memory?
This would cause an intterrupt every time successive memory accesses were in

Indeed. In fact, when you put in a 4GB module, the BIOS reports
that you have 1GB of "4GB+ memory" (a possible indication that the
last gigabyte is mapped into some special space). Maybe there's
something like PAE going on. Anyone know what might be up? (Copying
