The patch is no longer usable as the do_suspend function now uses "/usr/lib/hal/hal-system-power-pmu sleep || echo -n "mem" > /sys/power/state" instead of the "pm-pmu suspend" that, my guess, was being called when the patch was written. The error comes from "/usr/lib/hal/hal-system-power-pmu sleep" and seems harmless as it just prints out the error message and exits. Seems like the problem might be elsewhere now.
