The i386 qgsrasterlayer.cpp code somehow did not make it into the 
binary. libqgis_raster.1.0.0.dylib is universal but qgsrasterlayer.o is 
not! The link should have failed due to missing input. Note below that 
the ppc code size is 5x the i386 code size.

$ lipo -detailed_info src/raster/.libs/libqgis_raster_la-qgsrasterlayer.o
input file src/raster/.libs/libqgis_raster_la-qgsrasterlayer.o is not a 
fat file
Non-fat file: src/raster/.libs/libqgis_raster_la-qgsrasterlayer.o is 
architecture: ppc

$ lipo -detailed_info src/raster/.libs/libqgis_raster.1.0.0.dylib 

Fat header in: src/raster/.libs/libqgis_raster.1.0.0.dylib

I will recompile qgsrasterlayer.cpp and send you a pointer for i386 
testing. Until then, the following might make it in run in ppc emulation 
mode.

$ lipo qgis.app/Contents/MacOS/qgis -thin ppc -output 
qgis.app/Contents/MacOS/qgis
