{sigh}

I'd really like to just drop this whole driver as I feel it's _way_
behind whatever anyone is really using "in the wild".

Actually, I doubt that anyone even uses this thing, do they?

Any objection to me just dropping the drivers/staging/dream/ tree?
People should be working on the chipset-specific driver tree here
instead, right?

Pavel, it looks like you're not doing any dream work anymore, any
problems with me dropping it?

thanks,
