Modified Files:
	syssrc/sys/arch/mac68k/dev [scottr-mac68k-wscons]: grf_compat.c

Log Message:
Improved emulation of grf devices:

 - sync return value for unsupported ioctls with legacy grf driver
 - returning (-1) from grfioctl() is hardly appropriate; return EINVAL
   when we are given an unknown ioctl  (duh)
 - don't add the displayable region offset in grfmmap(); apps handlj
   this themselves
