Dell Wireless Vista Ultimate x64 BSOD: X64_0x3D_bcmwl664+580b4

>Hi there,
>
>I recently ordered a new Dell XPS M1530 with Vista Home Premium. I upgraded
>it to Vista Ultimate x64 and ever since I installed the drivers from Dell for
>my wireless, I've been receiving seemingly random BSODs. Here is the
>information you may find necessary:
>
>Device Name: Dell Wireless 1505 Draft 802.11n WLAN Mini-Card
>Driver Title: "Broadcom Extensible 802.11 Network Adapter Driver"
>Driver Location and Name: c:\windows\system32\drivers\bcmwl664.sys
>
>As a note of mention, this same issue happened to me once in Windows 7 Beta
>1 build 7000, which I installed on a separate partition on this laptop. Any
>ideas or help would be greatly appreciated. I've already tried searching for
>updated drivers (via Windows Update; I haven't Gooooogled or searched Dell's
>site yet) and run through all the, "Problem Reports and Solutions" scenarios,
>sans disabling auto-tuning or the device altogether.
>
>Thanks for your time and any help,
>Stephen
