since my graphic string and my sound string still don't work: What exactly is it all about those configuration-tables. I can see in your screenshots that you have several tables in ioreg? I can only see two (the last two in frantisheq's screenshot starting with EB9D) here...
Thanks for any help and clarifying
first for graphics, second for network (TM fix) and the third for sound
Ok, solved! I got it working, finally. Problem was, that somehow my com.apple.Boot.plist was sort of broken (?): Property List Editor couldn't open it. I used to edit it in terminal with nano before. So obviouly, I messed it. Now both graphics (my 7300GT) and sound (ALC882) work perfectly without nvinject and ALCinject. Thanks you all for your help and thanks for the great tool!
One more question related to this topic: You mentioned a HPET device. I dont' find it in IORegistryExpl. Why? My board should have it (ICH7).
