Its behind the runway. To verify it, i wrote a little piece of code and
voila - it shows up:

"BC Runway Port, type 0xc [I/O Adaptor], sv 0xb" at mainbus0 (type c, sv b, hv 7
) offset ff88000 not configured
==> mbattach: [8] iostat = 0x40
==> mbattach: [8] io_io_low=0xfffff100 io_io_high=0xfffff180
==> mbattach: [8] ioa real io_io_low=0xf1000000
==> mbattach: [8] ioa real io_io_high=0xf1040000

 sv c, hv 11) offset 103f000 not configured

cpu0 at mainbus0 offset ffa0000 irq 31: PCXT' L1-B 120MHz, FPU PCXT' (Tornado),

Its not recursive yet, i will have to make it recursive to get everything
down in the busconverter/busconverter/busconverter/... path.

The runway is obviously already initialized by the PDC.

These mechanisms are nowhere documented, (or are they ???) i discovered 
them by looking at the Debian code and i wonder where _they_ got it from.
