Broadcom 4311 Drivers for XP Pro x64

I have a Gateway MT6451 notebook that is my main workhorse.
It shipped with Vista, which is way too slow for my taste so i "upgraded" to XP Home.

Well, it's not stable for some odd reason, so i decided to install XP Pro x64.

There is 1 driver i can't find anywhere the drivers for the Broadcom 4311

I had it working fine under 32-bit XP home, but no dice under x64.

any help is appreciated. i did notice the driver i used under xp home was x64 and x86 but it won't install under x64.

i hate drivers but what can you do.
