Hi Akio,
Dom0 boots with this, but booting a domU w/ the -xen kernel does bad
things:
Xen p2m: assign p2m table of [0x0000000000000000, 0x0000000100000000)
Xen p2m: to [0x0000000100000000, 0x0000000103ffc000) (65536 KBytes)
XENBUS: Device with no driver: device/console/0
Unable to handle kernel NULL pointer dereference (address 0000000000000000)
