The truth, to relate to your title, is in fact, that there is no fix that works for everyone...
I've read a lot on the original German topic for white rabbit, and the author Einsteinno tried to implement such a fix with a little help from his fellow beta-testers.
The conclusion was, that for almost everyone who tried any of the fixes another one or none worked... Maybe it's the build of their Defys, maybe bootloader or kernel or something else.
It seems you have tried a few and if none off them worked so far, you might have to wait a little longer...
