Check out
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/pvlans.html#wp1130380
for more information on configuring PVLANs for trunking.  You're going to
want to configure VLAN 101 as your Isolated VLAN inside the Native
(Primary) VLAN, and you'll enable the trunking on the secondary VLAN. 
Something along the following will give you the expected behavior:

switchport mode private-vlan trunk secondary
