Just verified it: works with current build (2008-07-12, grml_sid_latest.iso) 
without any problems.

Thanks for reporting, azhag!

Error with udevtrigger is fixed.

Unfortunatelly live still fails while booting, looks like it's caused by 
something else. As soon I will have any "suspect", I will let you know. :)

There is no `/sbin/udevtrigger` (symlink to `/sbin/udevadm`) in 
udev_0.124-0grml1 package.

Probably it causes boot failure in live created by grml-live -- there is an 
error:
 '/script/init-premount/udev: /script/init-premount/udev: 20: udevtrigger: not 
found'
and few seconds later init exits to ash.
