We're using the tg3 driver...so maybe this catalyst switch is not the 
crappiest piece of equipment in the world after all. We'll see I guess.

But I already had iappend 1 in my default file, and I tried moving it to 
the top (if that makes any difference) but there's no luck. So I'm going 
for an ipmac file. We only use dhcp for pxe-booting anyway.

Yeah, I know about the .post script from the mailling list. But I can't 
figure out how to put them in the initrd (Though  I've read about the 
makeSomething-script), and I have no idea how to --merge a new symlink?

We're running it via PXE-boot only (well the sender is booted from cd-rom)
I will try the ipmac file, this however I don't know where or how to put
