It would be best if the asr could be made to work, it could save me
a couple of grand. How hard is it to get hold of datasheet for the
2010S card?

Yes, I've PAE running in 4.x. If possible, I'd like to commit it back to
the tree, what do you think as a release engineer? I'll start backporting
aac driver 64 bit support, when I'm done, I'll run it through you, how
does it sound?

Thanks, really appreciate your help!
