Two quick SX questions (heat and speed)

Two quick newbie SX questions for you guys...
1: Is it normal for a SX28 clocked at 50mhz to get somewhat warm? (The SX-key gets warm too when using its clock for debugging)
2: What's the lowest clock speed for reliable serial communication at 9600 baud? (I'm aiming for 4mhz)

2. So long as you're using an external clock and using SERIN and SEROUT (i.e., bit-banging serial inline) you'll have no problems with 4MHz; I ran a quick test and the compiler was okay with SERIN and SEROUT as fast ast 250Kbaud at 4MHz. If the baud rate is too high for the specified clock rate the compiler will complain.
