modprobe of busybox was/is too broken. :( But when switching to the
initramfs approach we shouldn't have to deal with that any further.

Depends on the progress of development in the next few weeks.

If we have a grml 1.1 release quite soon, the initramfs-approach
might hit 1.2, if we "delay" the 1.1 release some further weeks it
might be part of 1.1 already. (I expect to take a closer look at
live-initramfs at this weekend at Froscon - see
http://www.mail-archive.com/grml@mur.at/msg01328.html for details.)
