Hope the mods don't mind, but there have been so many questions on this, I thought I should post. Maybe this should be stickied.
I'm rooted, S-ON, CleanROM 1.7 GBE and using the process and apk from here:
[MOD][07.14.12][Hotspot AP mode fix - LIVE on android-wifi-tether site][GB/ICS] - xda-developers
I can tether my Nexus 7, laptop and my girlfriends phone.
As it says, there is also information and how-to for ICS. This was what I had been looking for for a long time.
