Paolo,

As said in private email you can change the port 80 passthrough to
disabled only on those hosts that have broken port 80 (you can find the
blacklist at arch/x86/kernel/io_delay.c).c

Actually I read the code more and, since pv_ops is actually disabling outs to port 80 if the guest is sufficiently new, it may even make more sense for easier maintenance to remove the port 80 passthrough on Intel processors as well...
