Good to hear (I have a Lion here).
I was feeling pretty stupid already because nobody else
seemed to have had problems :-)

It definitely appears that something is wrong with interrupt assignment.
drivers get IRQ 0 and can't do anything with it ...

I have finally got a printout of some boot messages with a serial console.
There are very few differences between a 2.4.5 and 2.4.7 boot, but those
that appear relevant are related to failure in interrupt allocation
(note that the serial driver also says "irq=0").
