Measure boot time using ttyUSBx on host mach?

[Ranjit Pillai]

Scenario
don't have a debug board. Currently NAND have uboot,
kernel(2.6.29-rc3-v24), QtMoko

Can access uboot using ttyACM* but would love to have an output like
http://lists.openmoko.org/nabble.html#nabble-td4204941 with ttyUSBx on
host mach using terminal program like neocon/picocom. Is it really
possible to have ttyUSB enabled all the time of so how to acheive
that?
