Here is what I have done. I have downloaded the zip file 0.90. In that zip are a file folder entitled src. Also there are three files: battery.o, powerMgr and start.sh (actually 4, including the README). I have created the /lib/modules/2.4.19-rmk7-pxa2-irex1/kernel/drivers/irex folder and in the /irex folder I have placed the battery.o file. In the already existing /usr/bin folder I have copied the powerMgr file. In the /home/root folder I have placed the start.sh file. I have then turned off the device and turned it back on (reboot). I still only get 12 - 14 hours out of the batteries (2 - 2800s). Am I missing something? Am I supposed to do something with the /src directory and subfiles in the zip? PLEASE HELP THIS DUMMY!
