I've been thinking.
If the issue is something else entirely...
I am not sure where yet you should look or whom you should ask for help from...yet.
Not until we know exactly where the origin of the problem is coming from.

Since the symptoms you are experiencing are just that..."symptoms"
and BME MAY just be responding to the real issue...
which is elsewhere...

That being said..
Now... if the issue is BME related ...
the one guy here who knows ...more than all of us put together on the topic of the BME...
Is Pali.
Hell ....he wrote the BME replacement for the stock BME for our n900's.
He may be able to help track down the issue..IF it is BME related...
If the problem isn't BME related...at least you know that you can rule out BME being an issue or culprit...
and go from there and narrow the field on what and where the problem is springing from.
