Fixes in this version include:

1.	Changes to the device negotiation code to make sure we don't try to
	negotiate something with a device that doesn't support it.  We
	now peek into the INQUIRY data to find out exactly what a device
	does or doesn't support.
2.	We wen't back to PIO instead of MMAPed IO on Intel architectures
	for reliabilities sake.  This may change again in the future, but
	for now, that's the way things are.
3.	Added the aic7xxx_release function to avoid memory leaks when
	unloading the driver as a module (thanks to Matthew Jacob for his
	code contribution on this).

That's all I specifically remember.
