Fix building the m68k kernel

Browse Source 
* Restructured the vm support code to align with the changes done to other archs.
* Not completely finished, but the kernel loads and panics. I had this sitting on the disk anyway.
* Only support 040 for now, 030 will need to be added back.
* This commit is dedicated to Jack Tramiel who passed away away last sunday:
