i plan to work on some improved scripts for the modprobe issue in
jaunty, what you can do today is to provide a fixed list of modules
in /etc/initramfs-tools/modules, that speeds up the probing stuff
already ...
one (really evil) option that can go hand in hand with such a hardcoded
list is to disable /etc/udev/rules.d/90-modprobe.rules in initramfs and
enable it later again, that way you can get rid of *all* modprobing at
boot (but mind you it really needs a working module list) ... that can
gain you massive speedups but indeed makes you lose a lot of
flexibility ... 

(dont do that at home if you dont know what you're doing !!!!)

i will write a spec to discuss a possible enhanced profiling mode with
something similar for the UDS and will announce it here before
mountainview ... 

ciao
