revert this change from early this year. it appears the
changes macallan@ commited to fix FIRMWORKSBUGS issues in openfirmware() have fixed the hangs seen on PegasosII. hooray! --- Log Message: workaround a problem with the pegasos firmware interface: attempting to use /dev/openfirm on this machine hangs hard. this isn't a new problem, and i've been meaning to try to figure it out for years, but it's become a problem since the xf86-video-radeon driver gained code to look for the macppc model using this interface. this is why xorg-server 1.18 and 1.20 hang recently on the pegasosII. this change is fairly ugly but i couldn't think of a less ugly method to avoid /dev/openfirm working just on this one platform. introduce new __OPENFIRMIO_OPEN_CHECK_BROKEN macro and associated __openfirmio_open_check_broken(), and use them in the new openfirmopen() to fail opens. include proplib.h in macppc and ofppc autoconf.h since they use it. ---
