My sid pbuilder is currently somewhat hosed (due to lack of current
aptitude on amd64). 8-/ I will re-check when it's fixed.

Perhaps it's also somewhat related to the X server.  Most of the CPU
usage during scrolling is in the X server.  CPU load with Emacs 22 is
very low, though.

On my system, the redisplay activity is almost noticeable.  There is a
slight effect, as if it were painted top-down (similar to those slide
effects in presentations).
