Ok, I have a 21140 too. So it should work (I also have compiled kernels
with root on NFS on this machine, no cross compile)

You might have to tweak the main Makefile for cross compiling, this
depends on which kernel you are using, and how egcs (in which
directories) has been installed.

However the following:

	make ARCH=ppc CROSS_COMPILE=<correct directory name> 

should work most of the time.

No, I don't think so. Ah, and BTW the kernel I put on the ftp server has a
serial console: all message will be logged to the serial port and you can
also set a getty on the serial port in /etc/inittab:

S0:12345:respawn:/sbin/getty -h ttyS0 DT9600 vt100
