The "pci" and "physdev_dom0_hide" parameters take PCI IDs as
parameters (Bus
number:device number:function, as displayed by "lspci"), not ISA Bus
Port
numbers.

AFAIK sharing of ISA resources isn''t implemented, so you''ll
have to use a PCI
Serial Card or an USB->Serial converter if you want a real serial port under
domU
