int_osx_receive_prim() in gsm-fw/gpf/osx/osx.c: there was an error in the reconstruction of this function from disassembly in the logic that implements special handling for MPHC_RXLEV_REQ messages. The code is now fixed to properly match what the binary object version does; with this fix the firmware now performs the power measurement phase correctly and the initial network registration succeeds.

During some of my debug sessions (wild goose chases after difficult bugs)
I hacked the bloody hell out of some Nucleus modules, trying to instrument
them to catch the bugs I was after.  This directory is a stash-away place
for such ugly hacks.
