The patch has been tested and passed on fam10 board. 
I added an acked-by line to it, but I didn't review it. I didn't trace
what happened in these patches and don't know what they mean. I just
tested it. If it is appropriate,

I guess fam10 code allocates a separate register for prefetchable
memory.
K8 doesn't.  Since I didn't add IORESOURCE_BRIDGE to the prefetchable
resource, anything prefetchable didn't get allocated (look for ERROR:
...
not assigned messages)

Here's an updated patch.  Thanks for testing.

The last piece of the patch isn't necessary, but it would be nice to
unify
the K8 and fam10 code more than they are.

Thanks,
Myles
