[Grml] The installed GRML boots very slow

Hi,
while checking out your list archive, I found that this was brought up
some months ago, but I repeat it:
I installed the release candidate of GRML 2008-11 on my desktop machine,
and since that I had to observe a slow boot process.
My hard drive start spinning and then stops for a long time till it
starts moving again. I guess that in the meantime there runs the
hardware detection. But why lasts this procedure so long?
Below I put the results of:
cat /proc/partitions
and
ll /sys/block

major minor #blocks name

Anything wrong with that entries?
What can I change? I remember that deactivating udev detection is no
good idea.

When booting with noudev the problem isn't visible?
If so try finding out which driver takes so long to initialize.
Look at output of lsmod of a system running without the use of
noudev and manually load the drivers. Also check out dmesg and the
timing information at the beginning of each line.

How can I change boot options on an installed system?

I've checked taht, but I don't really understand what all the entries

May I send you the output?
