There are 2 places we use the hard_reset code.

1) Right at the top of hardwaremain.c before enumerate_static_devices
   in case we get into LinuxBIOS for some odd reason.  Say the OS's wants
   to do a reboot.
2) In device/hypertransport.c where we to do something to get the HT settings
   on an I/O chain to go into effect.

The easiest thing to do is a global flag that says we need to reset
the system in hypertransport.c and then to put all of the reset code
after dev_enumerate.

There are still some details there to be worked out, but...
