Observing that nothing else in the file seems to look at read_psl, I
decided to try the "brute force and ignorance" experiment of just
commenting out that line and seeing what happens.

The HVM now starts, and seems to pretty much run as normal. I can see
evidence of activity from the disk light and so on as the domU starts
up and runs, but clearly something else is not right because the
Xserver gets very sluggish to respond to the mouse, and quickly
freezes.

I'm guessing there's some mismatching spl or lock handling somewhere
in the path, potentially introduced with the merge of idlelwp?
