Ok after further testing, and attempting to use the same device on another machine, it turns out that the oops is an SMP related issue. Attempting to use the speakup_dectlk module on another machine with the serial device states that the device cannot be found, even though I am able to send it data using minicom, and get other user-space apps to talk to it.
