Well, thats a break through :-) If I understand you correctly, the 
destination host actually receives the ARP packet and responds with a 
packet.

That should means that the outgoing DSA tagging is working.  Although I'm 
not sure about the incomming...

I think that the "VLAN map/table" has gotten a wrong name as it does not 
really determine the VLANs, it only says who can talk to whom.  The switch 
does support a real vlan setup, but its deactivated in Lennerts driver, as 
I guess he wants Linux to handle the VLANs.  (I use the real VLAN setup 
extensively in my driver).

I have also checked the different registers setting, and things looks 
quite alright.  Although I'm missing the register datasheets for the 6131 
chip, I found that I only have part 1 of 3 crap...

I did find that the 6095 and 6097 does differ in the way DSA handling is 
done, as the 6097 supports Ethertype DSA and 6095 don't.  But the 6131 
driver looks like it does the right thing for the 6095.

Is lan1.1 up and have you given it an IP address?
(could I get a 'ifconfig' output?)

Are you sending packets with VLAN tags?

Don't think the switch needs a MAC address...

Don't think so...
