Start debugging the various bits of kernel startup that happen before 
the framebuffer gets initialized. A serial cable attached to one of the
serial ports (with the console=ttyS0 or console=ttyS1 kernel options) is 
helpful there. If you can't hook up another computer to the serial port of
your Mac, you'll need to re-implement the 2.0.36 early text console 
feature  (basically, head.S needs to export the console output routines in
a way that they can be called from C code. See the 2.0.36 source for
details).
