He has plenty of CM9/ICS stuff on his github. You can pull/build from that.

That is for CM7/GB, but you can pretty much follow those directions and just pull the sources for CM9/ICS instead.
I believe you should be able to change this:
Code:
repo init -u [URL="git://github.com/CyanogenMod/android.git"]git://github.com/ikarosdev/android.git[/URL] -b gingerbread
to this:
Code:
repo init -u [URL="git://github.com/CyanogenMod/android.git"]git://github.com/ikarosdev/android.git[/URL] -b ics
I think that is all you need to do to pull the ICS source instead of the GB source. You might have to pull some stuff from the Cyanogenmod git as well (but I doubt it). I have not done this myself, so I might be leaving something out. I don't really have time to mess with it much for a few days, but I can take a closer look if that doesn't work and nobody else sets you straight in the meantime.
