I don't have a lot of managed switches around to do extensive testing. 
The closest test I can do is on 5.8 with VLAN 2 and different IPs. 
Based on that, everything seems like it should work.  Since you're able 
to set up the addresses on the interface without a bridge, the 
likelihood of a driver problem seems fairly low.  Did you ever send the 
output of "brctl show"?  You should definitely be able to run tcpdump on 
eth0.20 and see any traffic on that interface.  You said that you saw 
none when you tried to ping the Linux host from the network.  What about 
the reverse?  Do you see data go out eth0.20 when you try to ping an 
address in the attached subnet from the Linux host?
