Note that the random seeks on disk can be avoided by a technique used by Windows XP: that OS 'remembers' what sectors of the disk were accessed during boot, and places them close to each other on disk. This is a kind of optimized disk defragmentation. There is a lot of performance to be gained with this technique, I think.
Also, this is desperately needed. Booting Linux is slow. Very slow. On a server this is no problem, but it's not acceptable on a desktop which is switched off every night.
