Not yet really. I first wanted to see what options there would be. Would things
like that fit into the linux-firmware package? Or is that restricted to only fw
bits themselves?
Is there still time to come up with a new package for Maverick? When the general
opinion is to have a universe package (e.g. gobi-loader) I can do that.
