i (sadly) don't think there is a lot to you can speed up in the
initrd->init script.. it's all loading modules and
initializing/mounting the partitions... speeding it up means excluding
modules or removing them completely and compile them in the kernel
(which would be better for the default modules like lvm, sata and
pata)

LinuxBIOS would give some seconds speed boost.. but that's not really
a solution that is possible for anyone.

btw.. it would be nice if bootchart could run before nash.. and right
after grub.. Thosefirst few seconds in bootchart (about 7 in my case
now) seem to be waste but seem to be RedHat Nash running...
