The minimig is also just "emulating" the custom chips of the original Amiga. Don't forget that. It's just done in hardware instead completely in software.
So, probably you will get something close, but not completely.
On the thought of a pci Amiga board, seems pretty redundant to me. like someone earlier posted WinUAE is good enough to emulate most of the Amigas quirks. And it will get better and better.
And yes, indeed, Amiga has to go opensource, the only way to survive for the system.
