Well, it's basically telling you that there is no ELCR to dink with to try and
do any changes, so it's not making any changes at all. Using level/low for
IRQ 13 does seem very broken since IRQ 13 is used by npx0 and should be
edge/hi. One thing to look at is to see if Linux thinks this box as an ELCR.
