[PATCH] Add support for Winsystems PCM-MIO PC/104 based multifunction board

Hi,

This is a patch to add a new driver to comedi, the 'pcmmio' driver.

This driver adds support for the Winsystems PCM-MIO PC/104 
based multifunction board.  This board has 16 AI, 8 AO, and 48 DIO 
channels.  The driver is almost complete -- it is just missing 
asynchronous mode for AI and AO.  But synchronous mode works fine.  There 
is even IRQ support for the DIO lines (edge-triggered interrupts).

Please add this to CVS at your earliest convenience.. thanks!
