capturing vlan traffic on linux

Box is Linux 2.6.12 kernel tcpdump 3.8 libpcap 0.8.3 Intel e1000 NIC Long story short, 1) when sniffing on the vlan tagged interface (eth0.5), I can see inbound and outbound traffic, but the ethernet frames are not tagged. 2) when sniffing on the physical interface (eth0) I can see only one direction of traffic (outbound I think), and again no vlan tags. Is it not possible to sniff traffic with the vlan tags if the traffic is destined or generated by the host? Or do I need to upgrade something?
