Scoot Head, if you check these two links you'll find a reference for the Titanium LCD: AU Optics Corporation - PN B152W01 (works in all Titanium models). Looking at the other link, the same B152W01 is advertised for the PowerBook aluminum.

I would be not surprised that you could swap the LCDs (of the same resolution) between the two series minus the 1.67 high resolution PB G4. I often swapped iBook G4 LCDs with iBook G3 ones

.To Sascha: if you want to know your LCD model:

- open Terminal application

- paste this line:

ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

-hit the RETURN key

Once you have the information, search on Google to find if you can get a match with a model of Aluminum PB LCD. Good luck !!
