For a start:

That line

pcmcia: Detected deprecated PCMCIA ioctl usage from process: hwsetup.

has not much to do with pcmcia_cs. It is just that hwsetup uses a deprecated
interface (new one is sysfs). Is this message still showing up with the newer
gentoo-version? I seem to recall that hwsetup got fixed meanwhile, but I may be
wrong here.

What about these lines?

Do they still show up with the latest kernel? Is this a known problem with this
laptop?

So much for a glimpse, maybe I'll have a bit more time tomorrow...
