It is not Paul's job to fix PAE. It is job of whoever broke it to do
so.

If it is broken with 2GB of RAM, it is clearly not the known "lowmem
starvation" issue, it is something else... and probably worth
debugging.

So, Paul, if you have time and interest... Try to find some old kernel
version where sleep test works with PAE. Hopefully there is one. Then
do bisection... author of the patch should then fix it. (And if not,
at least you have patch you can revert.)

rjw is worth cc-ing at that point.
