FS#173 - X uses 100% cpu in low power mode

After 10 minutes in low power mode X seems to go nuts and use 100% CPU. Obviously this is bad ;-) 14MHz isn't *that* slow, so there's obviously something getting wedged. I haven't been able to figure out exactly what's happening, but the fact that it always occurs after exactly 10 minutes suggests its power management related. Maybe we're getting stuck trying to kick off the screensaver, or something? Hacking do disable screen blanking shows that, unsurprisingly, the screen freezes at the same time X goes AWOL. Pressing the power switch brings the device out of low power mode, though there is often a few seconds additional delay as the event handling scripts take longer than normal to run because the CPU is already busy. I've attached the results of top -b -d 60 > toplog & while sleep 60 ; do cat /proc/loadavg; done > loadlog
   loadlog (0.4 KiB)
(application/x-gzip)    toplog.gz (6.6 KiB)
