Well, I was hoping not to have any Mac OS on this machine except a
full-blown Mac OS 9 when needed. This would allow me to Quik-boot Linux and
set OF to use /AAPL,ROM when needed through my serial console. I don't
believe I can choose between booting Linux/Mac OS in any other system using
a serial console (only built-in monitor).

Well, I usually use the built-in one, but when I disabled CONFIG_FB, I
didn't use a display, I just used my serial console / telnet.

I haven't tried the 2.4 tree because I didn't know how reliable it was. I
guess it's time to try it now. How/where do I get it?
You say that these changes didn't make it into the kernel.org tree, but
where do I get the BK images? Is there a way of getting it through
FTP/HTTP?
