imho using bootchart is probably the best way to go because it will catch all 
parts of the system, not just the parts we write. it also avoids a lot of 
duplication of effort that went into making bootchart in the first place :)

first, by "KDE SC" i assume you mean Plasma Desktop? the Plasma Netbook would 
be another interesting target, but one things at a time i suppose.

measuring Plasma Desktop with and without kwin desktop effects might be 
interesting as well.

to know if such a solution works will require measuring and more measuring, 
but i think we'd all be very interested in the results.
