Which way of stopping the serial layer from grabbing the port did you have
in mind?

If I call uart_remove_one_port, I'd need to get struct uart_driver *drv
and struct uart_port *port from somewhere. Also, it'd be quite ugly to
have /dev/ttyX appear and magically disappear during boot (since 8250 is
compiled in with most distro kernels and my driver would be a module which
would be loaded much later).

The only alternative I could think of would be to get the serial core to
check with acpi_check_resource_conflict for ports that have not been
discovered via PNP/ACPI?
