Hi,

this patch creates a dummy IO ports memmap entry for domU.  With this, IO 
accesses are trapped (and displayed) by Xen.  Previously they were polluting 
memory and could result in random crashes.

It is also wise to add options such as 'ide0=noprobe' on domU linux command 
line to disable such accesses.

Tristan.
