Which kind of preemption? CONFIG_PREEMPT was traditionally known to be problematic on PPC, though CONFIG_PREEMPT_VOLUNTARY seems fine here. > - GNOME takes *forever* to start, from GDM on.

The CPUs should be about on par, but the memory bandwidth on the PowerBook is probably lower, and the HD speed might also be important. > - The sound gets skippy on fairly innocuous things like scrolling or tab > switching in Iceweasel.

At least the 2D parts of it (i.e. the actual application window contents, as opposed to the final compositing done by compiz) are most likely done in software actually. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer
