There are a number of techniques used by CE vendors to get fast bootup time. Some CE products boot Linux in under 1 second. Sony's best Linux boot time in the lab (from power on to user space) was 148 milliseconds, on an ARM chip (running at 200 MHZ I believe).
Every product I know of that boots in under 1 second does it by completely eliminating RC scripts, and using a custom init program.
For anyone interested, CELF has some resources on this topic at: http://tree.celinuxforum.org/CelfPubWiki/BootupTimeResources
