MAC-Address in Gentoo Live Kernel

[mbuchber]

Dear all!
I have managed to get the LiveCD (Gentoo) working on the Xbox with NFS-Mount of the rootfs. I use the following commandline in kboot.conf:
gentoo="/gm/VMLINUX initrd=/gm/initramfs root=/dev/ram0 cdroot=1 real_root=/dev/nfs nfsroot=192.168.1.1:/srv/tftp/gm video=xenonfb panic=60 maxcpus=1 loop=/image.squashfs looptype=squashfs console=tty0 nox ip=dhcp"

...which works wonderfully, except for the IP-Adress a XBOX (we have more than one) gets from DHCP. Somehow, the MAC-Address of the eth0 Interface turns to 00:01:33:44:55:66 when the kernel comes up, however, xell displays the correct MAC before initiating the boot process.
Can anybody help me? I suspect the MAC address is somehow hardcoded in the kernel - can that be?

Regards,
Michael

Yes, it is hardcoded indeed.
Linux Kernel does not care about the contents in nand at all... that means, it doesnt care about the smc config - where the real MAC adress is stored...
