Well, I am working on a PCI E820 hole thingie,
If this for the 4GB mem limit on pvops domUs?
but those patches are in the
infancy period. There are some fixes:

the initial domain 0 support (all in Stefano's tree).
I tried disabling the CONFIG_XEN_PVHVM with no change. (see the "2.6.37-rc1 mainline domU - BUG: unable to handle kernel paging request" thread.
Is that sufficient to eliminate the PnonHVM from the equation?
