Your line had a typo (the first ")" has to be removed), then I can get
the Grml menu (I've joined my 42_grml file for reference).

Thanks for the precision.
I still have a problem booting Grml, but I don't see exaclty what is
wrong and how it can work for you ;-) my Grml booting problem is that
live system doesn't find the ISO, because of problem in kernel command
line :
I get a kernel command line (from my memory) like :
apm=power-off quiet ... iso="/boot/grml/grml64-medium_2010.12.iso " ...
The problem comes from the quotes around ISO path, as set in 42_grml :
iso_path="/boot/grml/grml64-medium_2010.12.iso "
(I don't at first set CUSTOM_BOOTOPTIONS, I then tried with some
options, with the same result)
I have to remove quotes in iso_path definition to be able to boot, then
in that case, I lose optional boot options set in CUSTOM_BOOTOPTIONS).
I've tried to understand how Grml's Grub menu works (with variables like
"${isoopts}" "${kernelopts}", i'm not sure about the first variable
name), but I don't understand where these variables are set, and how to
have a correct boot command with optional BOOTOPTIONS.
Perhaps you'll have some ideas about this,
with regards,
Fred.
