Huh?! What does not work when running 'chroot /partition-with-grml-on-it'
and executing something like 'apt-get update' inside then?

Loading this kernel module does not take any noteworthy time. If you
really want to avoid loading of some special kernel modules just run
"blacklist $MODULE" on your grml system and it won't be loaded any
more. Regarding the "why seek to seek the floppy drive": even though
your laptop might not have a floppy *drive* you might have a
connector/connection for it on your motherboard.

To get rid of the raid stuff:

* Deactivate dmraid, mdadm-raid and mdadm in your
  /etc/runlevel.conf. This means it should look like:

  # grep -e mdadm -e dmraid /etc/runlevel.conf
  03      -       -               /etc/init.d/dmraid
  25      -       -               /etc/init.d/mdadm-raid
  25      0,1,6   -               /etc/init.d/mdadm
  50      -       0,6             /etc/init.d/mdadm-raid
  51      -       0,6             /etc/init.d/dmraid

  Notice: there's something related to this on our todolist, see
  http://bts.grml.org/grml/issue89

* Remove the sleep delay in the initrd:

  # apt-get --reinstall install initramfs-tools
  # update-initramfs -c -t -k $(uname -r)
  # lilo                                     # if you use it

  If you do not need the initrd at all just deactivate it in your
  lilo.conf/menu.lst.
