wdc_pioc.c has been broken since it was changed to use the new wdc driver. 
 I posted a PR about this over a month ago (with a patch), but nothing has 
been done about it.  The patch no-longer applies cleanly to the current 
version, but I managed to build a working kernel last weekend.  
Unfortunately, my RPC is at home so I don't have the patch to hand at the 
moment.
