Take a look at the TX39 Architecture simulator. It includes a
simulated serial port, interrupt controller, timers etc. A proper
solution to your problem is to write similar simulations of your
hardware devices. 

Probably better options is to use the eCos Synth target on linux, or a
Virtual x86 machine, eg Bochs, which will also have virtual serial
ports etc, or maybe SkyEye.
