Today I installed grml 0.9 (two times) to HD with grm2hd. If I boot with the CD the autoconf detects eth0 (e1000) and eth1 (ipw3945) from my T60 laptop. After install on HD and reboot the system just recognize eth0.

Ok, today I found the time to take a closer look at the problem at Lars' hardware (thanks for the coffee, Lars :-)).
JFTR: ipw3945 definitely has some race condition problems. To fix this problem on your Debian/grml system just take a look at my howto:
################################################################################ We want to avoid autoloading of the ipw3945 module at boottime, so we blacklist the module:
# cat /etc/modprobe.d/grml blacklist ipw3945
Now create a new initscript which loads the driver:
# cat /etc/init.d/ipwfix #!/bin/sh grep -q ipw3945 /proc/modules && rmmod ipw3945 modprobe ipw3945
Then make sure the initscript is used before /etc/init.d/networking is running:
# update-rc.d ipwfix start 34 S .
Notice a problem with /etc/resolv.conf? I couldn't debug it in detail due to lack of time but the problem definitely goes away if you do not use the package resolvconf, so just run:
# apt-get --purge remove resolvconf
We want to have persistent interface names so we bind ipw3945 to interface name wlan0 via udev (see 'grml-tips udev' for details):
# INTERFACE=wlan0 /lib/udev/write_net_rules 00:13:02:aa:bb:cc
Finally configure your WLAN device as usual via /etc/network/interface (and make sure you have CONFIG_DHCP=no in /etc/grml/autoconfig on your grml-system), for example it might look like the following for a WPA setup:
# cat /etc/network/interfaces auto lo wlan0 iface lo inet loopback
iface wlan0 inet dhcp wireless-mode Managed wireless-essid secret pre-up wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B down killall wpa_supplicant ################################################################################
