As I mentioned before: (AFAIK) the switch WILL remove the VLAN tag on an 
Access Port...
If I understand you right you want to send ALL broadcast packets to this 
device...
If so then maybe you need the TEE target in the iptables/netfilter 
framework...
Jan Engelhardt can help you with that... :D

I would:
- set up a new VLAN (2051),
- put the other side (this non-standard device) on an Access Port,
- copy (with TEE) the traffic to this new VLAN...
(Or just forget the first two steps and use an other ethernet interface 
and a cross-link cable :D )

Hope that helps. :D
