I seriously doubt that's the problem, because: - 32bit powerpc doesn't really do 64bit accesses ( unlike sparc for example ) and altivec is disabled for kernel code ( since gcc started using altivec for optimized, inlined memcpy ) - at least one of the putchar_aa() methods used memcpy() in order to speed things up by rendering scanlines into cached memory and then quickly copying them into slow & uncached video memory, which worked just fine everywhere I tried ( that is, mips, powerpc, sparc, sparc64 and arm ) > PS > I ordered Mac Mini G4, although serial console is hopeless... They're nice little machines which usually don't cause much trouble. Opening them is quite painful though. have fun Michael
