Bug#396169: linux-image-2.6.18-1-xen-686: Does not support PC serial ports

Passing the following option to the Linux kernel appears to have
solved this issue:


Also if I pass the following parameter to the hypervisor, Linux will
show only 2 serial ports instead of 4 (I believe my motherboard has
chipset support for 2) - still I bit confused where the other two come


My guess is that the CONFIG_XEN_DISABLE_SERIAL has no effect when
serial I/O is compiled as a module.

(note: I haven't yet tested this by talking to a real serial device,
just looked at /dev/ttyS* and dmesg).
