Normally (1.6_STABLE kernel) this looks like

kbd0 at zs1 channel 0: baud rate 1200
ms0 at zs1 channel 1: baud rate 1200
fdc0 at obio0 slot 0 offset 0x700000 level 11 softpri 4: chip 82077

I suppose I need 'makeoptions DEBUG="-g"' in the kernel config file?
(Kernel building right now.)

How would I proceed in gdb, since I do not get a core file? Is the kernel
linked for an absolute address?

Here's the output I get, just for completeness:
