So if are same, there is no bug in kernel driver (or in script is same bug as in kernel driver if exists).

So there may be bug in chip? Or I think that this chip can be configured (as written in datasheet some battery option can be configured). Could BME configure this chip to retrun "bad" values and BME monitoring bq chip and calculate its own values?

It's possible that BME was adjusted to include in it's calculations how differently was bq chip set for reporting values - my last post was all about that.
Unfortunately, fixing driver (or module or whatever
) is far beyond my skills - at least for now. Ho ever, i still can't understand why all values now are higher than it should be by stable same factor. Value reported by current_now is higher than it should be as it's multiplied by given x, and so is charge_full and charge_now also multiplied by exact same x. That's why internal calculations remain sane, but are wrong overall. As Pali noticed, it's most unlikely for TI to create custom chip with same name just for N900, still, bq module work as it should on netbooks/notebooks, and for us on N900 it reports wrong values. That's I'm sure for certain, just don't know why.
I think best i can do in such a situation - for now - is to measure as precisely as i can factor of drift (given x), then write a simple script that will calculate real values from drifted values and print them on screen. Then, of course make it public to those few who cares about precise real battery capacity (in mAh) measurement done using N900 only.

For all who has problems with bluetooth:
Only one bluetooth related patch between v46 and v47 is which fix l2cap NULL dereference in l2cap_conn_start. It was taken from: https://bugs.maemo.org/show_bug.cgi?id=10510
Everybody who has problem with bluetooth please run these commands (but after bluetooth problems apperes) and write here ouptut:

I included both patches to my git repository, but I didnt test it yet.
New kernel-power release wont be before july. Now I do not have time for testing kernel-power... (school)

My git tree is public, so everybody can clone and try to compile it!

And I entered an endless loop of reboots. Finally I had to reflash kernel and eMMC.
Now I've installed the same games, have those widgets again and it works like a charm. Finally I upgraded from kernel power v46 to v47 (I hate to stay out of date).
Conclusion: It could be whatever.
But I didn't install new things (or even change my homescreen, or anything) on my n900 in weeks, and it rebooted fine a few hours before i upgraded
I'll try reflashing kernel+emmc and putting v47 back, hopefully that fixes it
