[Greasemonkey] GM in sidebar

[user24 24]

Yo, got a GM script I want to run on a bookmark that I have set to open in
the sidebar, trouble is, GM 0.6.4 doesn't catch sidebar-ed URLs.
The script works fine when I load it in a normal tab, but in the sidebar,
there just ain't no GM.

Would greatly appreciate anyone who's got any ideas on how I can get my
GM'ed content into the sidebar; either by tweaking the GM xpi, or by doing
some GM scriptery that'll... erm.. get the content, parse it and load it
into the sidebar, when I click a bookmark? your ideas appreciated....
the first option seems easier.

In return for your troubles, I'll eat a cookie for you. How's that for a
deal, eh?

thanks,
