James Courtier-Dutton d83c671fb7 [PATCH] Creative Audigy 2 cardbus: Add IO window wakeup magic 
This adds the magic IO wakeup code for the CardBus version of the
Creative Labs Audigy 2 to the snd-emu10k1 driver.

Without the magic IO enable sequence, reading from the IO region of the
card will fail spectacularly, and the machine will hang.

My next task will be getting the driver to actually play sound without
distortion.

Signed-off-by: James Courtier-Dutton <James@superbug.co.uk>

[ This is a work-in-progress, but since it avoids a total lockup
  if the emu10k module is loaded on a machine with the cardbus
  card inserted, we're better off with it than without it, even
  if sound quality is bad right now ]
