And to prove that its not just this driver, I've now received a report
that it fails with the CF PATA driver on Zaurus. Should we make the
PATA subsystem select CONFIG_ZONE_DMA too, or should we give people
some grace period to fix the drivers as _everyone_ except you is
suggesting.

Please do the sensible thing. Make it warn for a release like everyone
is telling you to.
