Re: X fails to restart after suspend (RmInitAdapter failed!)
The 100.14.19 driver no longer supports NVreg_SaveVBios...
The previous release worked reasonably for me, using "options nvidia NVreg_SaveVBios=1 NVreg_UseVBios=1 NVreg_VbiosFromROM=1": suspend/resume worked, the text display was restored properly and restarting X worked as well.
With 100.14.19 I had to drop NVreg_SaveVBios and now restarting X after suspend/resume no longer works (dark screen, no reactions to keyboard, etc).
Will try without any module options to see if that makes a difference.
