Log:
Checkpoint. HalDisplayString is working and hooked up to DbgPrint.
We've now got reciprocal imports from hal working.
I've added a small hack, that being to relocate modules to 64k boundaries. This works
around ABI issues for
now.
Some warning suppression re: uninitialized values.
KdInit: make it possible to use a subset of the x86 debug targets.
