The "--undi" part should be irrelevant: all you need is bin/ipxe.pxe.

Unfortunately, undi.kkpxe is potentially dangerous: if a native driver exists, 
then it will start controlling the NIC without shutting down the underlying 
PXE stack first.  The .kkpxe format should only ever be used as undionly.kkpxe.

For a proper solution, you need to get the .kpxe format working.  To simplify 
matters, try using bin/undi.kpxe - does this show the same timeout behaviour?
