I'm having severe problems with my phone, bme replacement is one of the suspects. Is this enough to remove the bme replacement?

Code:
apt-get install bme-rx-51=0.8.55+0m5 dsme-thermalobject-surface=0.
0.1+0m5 hald-addon-bme=0.0.17+0m5 libbmeipc0=0.8.55+0m5

after multiple times of trying to calibrate I have been unsuccessful all the time. As reaching low battery, I turn on offline mode and turn display brightness to minimum while having the screen on all the time. I've also just let it die without changing any settings. I've also made it die while playing a video. All unsuccessful. Also I am sure the VDQ states 1 but idk it never calibrates. Help?

After strugging to calibrate battery almost a year I decided to take deeper look.
Correct solution is to calibrate according to instructions. Tried this two times but failed. VDQ turned to 0 too early. Next time i'll also disable modem and maybe kill some more proccesses.
Next was to fix status-area-applet-battery or hald-addon-bme to report LMD when /sys/class/power_supply/bq27200-0/capacity is empty and LMD itself has reasonable value but I went easiest way and just disabled Pali's code in bq27x00_battery kernel module.
Works fine for me as my Last Measured Discharge (LMD) is 1155mAh. When the calibration succeeds I'll probably revert to original module so this will be temporary workaround.

If you have same problem, ie battery needs calibration but LMD is something reasonable then you can install kernel-power==1:2.6.28-10power53 and use attached bq27x00_battery.tar.gz.
After coping bq27x00_battery.ko to /lib/modules/current/ just 'rmmod bq27x00_battery && modprobe bq27x00_battery'

To revert back just reinstall kernel-power-modules

Patches to Pali's patches:
