I understand editing of PSPBTCNF.BIN is needed, to make the PSP find the file at vsh/nodule.

Any help would be appreciated.

Thanks. :D

From what you've said, you pretty much already know the procedure... >_>
Can't remember exactly, but it's something like
- flash PRX to /kn
- modify the pspbt*nf.bin files to add the PRX
- flash the modified bin file
- pray for the best
