Ok then most likely you have managed to get the debugging printk's
compiled out or something like that.  It should be possible to insert
a -g statement into the build and then to step through the code execution
with gdb.  qemu appears to have support for gdb stubs.

The real interesting part is what is the debug level set to.  And you can
get that with port 0x80.

Maybe we are attempting to use cmos options and that is not properly implemented?
