No. It's 2 things. First the NAP must be disabled depending on the errata (7450 + L3), but also, neither the 7450 nor the 7455 support DOZE, they can only NAP or do nothing. Worst, on the 7455, it's bad to set HID0:DOZE as it actually has a different meaning. So let's split the can doze & can nap into 2 different features. >> pmac_feature.c : add an entry in the machine table for your machine >> based on OF "model" property. > >According to the Apple developers note just released for this machine its >model ID is simply "PowerMac3,5" which is unchanged from previous versions >and already covered in the pmac_feature.c file.
