@qzxcvbn:
First of all - remove all patches and addons to your system - even silly things as the wb backdrop.
Then I have some suggestions:
It might be some wierd issue with the Firmware on your BlizzardPPC, you could try flashing it with the latest official release which you can find
here.
You could also try to make the latest driver + latest CyberGraphX system combo:
Install the latest disk I gave you the link to earlier, then from the latest CyberGraphX v3 archive which I also gave you the link to earlier, do the following:
copy cgxv41_r71.lha/cgxbootpiclib/cgxbootpic.library to LIBS:
copy cgxv41_r71.lha/cgxsystemlib/cgxsystem.library.040 to LIBS:cgxsystem.library
copy cgxv41_r71.lha/cgxvideolib/cgxvideo.library.040 to LIBS:cgxvideo.libraryAlso, remove any old CyberGraphX settings from ENV:/ENVARC: before installing.
