Thanks for checking. In any case, powerdebug shouldn't error out if one or more of the information sources aren't present. Instead, on each tab, it should say which are the kernel config options typically required for information to be present for that tab.
e.g. on GPIO tab, if /sys/class/gpio is missing, just print "Typically, CONFIG_GPIO_SYSFS, CONFIG_FOO, etc. are need for this feature. Please ensure they are compiled into your kernel"
