I am currently on a Dell D600 running Windows XP w/ a Broadcom 570x, driver version 8.48, WinPcap 3.1, Ethereal 0.10.7. I have tried adding the PreserveVlanInfoInRxPacket registry key with a value of 1 w/o luck as suggested on http://wiki.ethereal.com/CaptureSetup/VLAN.
You might want to ask either Dell or Broadcom about this (although I suspect most Dell technical support people's responses will be "huh?").
I am connected to a Cisco 3550 and have configured it as suggested on http://www.ethereal.com/lists/ethereal-users/200507/msg00303.html.
You might want to see if you can try capturing with a non-Windows OS, to make sure the Cisco isn't causing the problem.
I have also tried entering a capture filter "vlan" and "vlan 123," but I am still not getting the 802.1Q header info. 

The capture filter will not affect whether you get 802.1Q headers.
