you should be able to add ioports="FROM[-TO]" to your xm command line or the 
config file in order to grant permissions to a range.  You can replicate this 
several times on the xm command line to grant multiple ranges.  In the config 
file, ioports should probably be a python list of ranges.

See tools/python/xen/xm/create.py for where this is parsed.

I've not used this myself but it sounds like it does what you're looking for!

HTH,
Mark
