Hi all,
Looks like I has solved second part of our problem - issues with AR applications (like Google Sky).
I just took /system/lib/hw/sensors.shadow.so from stock ROM and put it onto my phone. Now Google Sky works well. So instructions the same as was for the akmd2 binary: get from stock ROM, remount /system/, push onto phone.
I don't know how to create patches for CWM, but I believe that someone (Wizard?) will create one soon.
You can get stock ROM binaries there: [ROMS] Droid X 4.5.621 Stock Rooted / Stock Deodexed / Modded (1.6) ClockworkMod Flashable Updates by kY - Droid X Development - RootzWiki.
