Arrgh. That was it. ttyS0, not
ttys0. Now at least I get messages at the serial console.
But, I haven't booted successfully again (it did
boot once). And now, I don't get the "bling" indicating the gum has made a
bluetooth connection to the laptop.
It "hangs" right after "Freeing init memory:
64K". Five times in a row, it hangs at the same place.
Thanks for all the great help!
