well, you could always switch over to the Reiser file system (I had mandrake on reiser and the thing was lightning fast at boot time. If you remove a bunch of modules that you don't use, modularize the ones you load occasionally (like scsi drivers for your USB flash disk or your cdrom or your wireless internet card - let this one load after boot...after all, the internet is no good without a kernel).
Other than that, a magazine called Linux Format (it's a British publication, so you'll have to check at Barnes and Noble or Borders) has a lot of neat articles on how to speed up your computer in general...not just at boot time. Particularly the October issue (the current issue here in the states) has an entire section dedicated to memory utilization, processor conservation, and active compression.
Hope that helps
P.S. why do you need to reboot in the first place? FreeBSD AMD64 (I know it's not Linux, but my point will be made) on an Athlon 64 running as a http/ftp/NF server for the last...what is it....three-four months now....only down for 20 min. to upgrade from 4.8 to 5.1
