I hacked around with it for a while and found that the serial port always 
worked fine for running a getty but failed for the kernel gdb.  I suspect 
this is because the getty did more configuration of the sio port while 
the kernel just bit-bashed.

The solution was to turn off "plug and play OS" in the BIOS.  This caused 
the BIOS to do enough pre-configuration that everything worked.  Now I'm 
debugging at 115200.
