When you get an "access of bad area" oops have a look at the DEAR
register (I think you misspelled it as DAR above).
0x3f9 is the base address of COM1 on an x86 machine
(http://www.sput.nl/hardware/io.html). My guess is you've got something
wrong with your UART code. I believe this is where your (current)
problem lies.
Just a guess.
