Mmm, weird. What does syslog say?

You don't need (or should?) do the vconfigs yourself. They are done by
the interfaces file automagically.
If ifup doesn't recognize the vlan, then please add the correct
vlan_raw_device statement.

Dunno. You could run into problems if your network card can't handle
larger than normal frames (a tagged vlan increases the frame size by 4
bytes). This is usually a hardware limitation...
