Thanks, I cheated a bit and installed Gallery ICS app from market and set to open by default. It works great so far. I have posted similar question in swap thread so maybe someone else has come across same issue. I can deal with it for now, wouldn't want to lose the extra space. I made nandroid backup prior to installing kernel, but I need to do some research before I restore it. Does that backup all user data and settings?
Yes if you do a full backup it has /data (settings, apps, data) /system (the rom, apps included and data) /boot (ramdisk and kernel) and /cache and whatever else.
Advanced restore allows you to choose which of those is restored. Boot should be restored with its system for the matching modules for wifi, data will remain unless wiped or restored as well.
Advanced restore system on the same ROM though, don't restore system from cm10 with data from flex reaper for example.
