Additional observation with respect to first,next shutdown:

With Option "AGPSize" "64", and booted with "nopat", X startup (from 
startx<enter> to functional desktop) is approximately 5 seconds, 
shutdown is 1 second as calibration times.

Booted without "nopat", X startup seems to alternate between 10+ and 16+ 
seconds and for shutdown -- the first shutdown after boot takes some 14 
seconds total, subsequent shutdowns settle at around 5 seconds.
