It should be enough to set a global variable "reset_needed" (maybe even
in CMOS) and check this, probably after all device drivers have been
executed and thus had the chance to set that flag.

When changing the parameters on Solo I always got it to one of the
reboots - My best result was to get it to the Misc Control reset before
it would hang hard.
