If you change the boot command to:
kernel mboot.c32
append sel4kernel console_port=0x2f8 debug_port=0x2f8 --- sel4rootserver
you may see the correct output.

Again, check *which* serial port you hooked up. Booting linux, and
doing something like
stty 115200 < /dev/ttyS0
echo foo > /dev/ttyS0
will tell you if you have serial hooked up right.
Possibilities are:
-- need to swap Rx and Tx lines on the connector
-- talking to wrong port (com2 instead of com1)
