Tang, The kernel config file (which specifies how the kernel should be built right) lists all the devices and kernel parameters. There are too many to list, hence I said start with the config flag that the parsec x86 kernel uses (see the parsec gem5 from UT-Austin tech report). If your not sure if the device is supported, I would just say no, and set the parameter to 0.
