I've got a 7920 and I would like to see Pacemaker supporting it. If I
can help by testing this patch, or the one on bugzilla, I'd be more than
happy to, but for the moment, I'm to ignorant to apply it to my code and
not being a C-programmer, the short explanation below doesn't clarify it
to me. Would welcome some directions on how to proceed with this (and
how to become a good patch tester)
Thanks,
Sander
