check http://maemo.cloud-7.de/maemo5/usr/local/sbin/ , particularly see how bq27k-detail2 does # v1.2 tries to deal with sysfs path changes on OM kernels, and supports N900 directly by using find and, for N900 ic2tools: #main dmppath=`find /sys/devices/ -path '*/hdq/*' -name dump` if [ x$dmppath != x ]; then dmpcmd="cat ${1:-${dmppath}}| tr -s '\n ' ' '" else dmpcmd="i2cdump -y 2 0x55 b|tail -n +2|cut -d ' ' -f 2-17" fi Alas for GTA02 smart battery there's no way to read out bq27000 via I2C (since that's onewire/HDQ), but maybe the improved spotting of dump sysnode location already helps. If above code runs into the "else" branch - i.e. didn't find the dump sysnode - then you might try to modprobe the kernel module that handles the HDQ, as explained in our battery-FAQ by Paul.
