What we would actually need...
...would be standards for on chip peripherals, so you will have a standard way of accessing external storage like harddisks or flash. Essentially what we'd need is an "IBM-PC", a well defined set of hardware devices which allow simple porting of operating systems.
It's like on the PC, if you don't have a special graphics card driver, you can still use VGA or VESA as standards to get enough on the screen to be able to debug your OS. Or USB-interfaces, there are only very few ways to interface with USB controllers.
