Jordan pointed me at a useful paper from this year's OLS, _Improving
Linux Startup Time Using Software Resume (and other techniques)_.  
It starts at page 25 of:

   http://www.linuxsymposium.org/2006/linuxsymposium_procv2.pdf

There's plenty of food for thought on general speedups there too, 
such as kernel execute-in-place[1,2] and allocate-on-write of 
.data sections[3].
