Wouldn't you need to multiply that by 3 for disabled and mouse-over effects?
Anyway, if I look at the first 5 items in xrestop for my current session, I 
see that they all are KDE programs that need more than 1MB pixmap memory. My 
konqueror instances need more than 2MB, and those are not displaying any 
graphics intensive web sites or image directories with previews. Kontact even 
uses 2.3MB in 489 pixmaps while I write this. What is that needed for?
I guess a tool that can display the contents of all those pixmaps would be 
nice :-)
