I am wondering too, but I doubt it would be too much. How many common icons 
are there really if you haven't exactly 10 konqueror instances? 10-20? So you 
save 32x32x3x10-20 = ~60K - I mean, it was a lot for a C64, but today? :)

For startup time it would help more if you have unique keys and a pixmap 
server to give it you in a go as the pixmap server could also preload pixmaps
that are used in every KDE startup. And it could cache them as one huge pixmap
on hard disc so he only needs one PNG->QImage transaction and then can split
them in several server pixmaps. I'm just not sure if you want D* for that or 
something fancy XAtomy :)
