I think that I've upgraded the SRM to the latest version. I can see the 
BOOTREQUEST from the 600au on the dchp server, in the dhcp server log 
and in the tcpdump log. And the dhcp server sends out the BOOTREPLY 
packet. But then nothing happens.

The same machine booted off a dhcp server on a NetBSD-1.6 (not sure 
about the exact version) without problems.

I have no idea why.
