 The problem is that the Nvidia NFORCE_MCP51 code is apparently broken.  
 FreeBSD 6.0 and below did not know about this chip/controller and the
 ata-chipset routine defaulted to generic ata, which works.  The patch
 below removes the check for the Nvidia NFORCE_MCP51 chip/controller
 and the routine will then identify the controller as generic and the
 kernel will boot.  Wish there was some way to have a boot-time option
 to tell it not to try the specific chipset patch.
