Ok, I reinstalled it, copied dsdt and got Chameleon, upgraded to 10.6.6 - but after restart it hang at "Waiting fro DSMOS...".
So I decided to reinstall it again, and this time use EDP. I installed KEXT pack for Nvidia D630, Chameleon and - drumrolls - it worked. Unfortunately, I can't get it to sleep, it hangs after trying to shutdown and so on... but after all it finally boots into OS X, now it's time to fix things that don't work
