bootp and all-ones source address

I am trying to use a 2.1.126 linux machine as a bootserver for a
machine that emits bootp request packets with the source address and
the dest address set to all-ones (255.255.255.255); this seems to be a
problem.

Using bootpd -d shows that the packets never get to the bootpd server
and no answere is possible. When testing the bootpd server with bootpc
on another linux box, the source address is sensible and things work
as expected.

I suspect that the packets with the funny source address get dropped
as martians somewhere in the kernel code. From the traffic on this
list I realize that earlier 2.1 kernels had a
/proc/sys/net/ipv4/ip_bootp_agent - but this no longer exists... Any
hint is apprechiated!
