Well, i have exactly the same problem here. I can't unlock S2 on Ubuntu Dapper drake 6.06 with newst cedega. I even consulted the LFS programmers which couldn't really be bothered. I asked them of the specifics of the unlocking procedure, and they said that they were using no special systemcalls that could be subject to failure on Linux/Wine/Cedega... I now have the answer, _ SOME _ windows registrys are accessed during the unlock procedure, from what i can read in here. THANKS for pointing that out! Theres now a possibility that my $$ isn't wasted!
