With my Lenovo Intel Wireless Card idea on a Mac Pro 3,1, on Monterey Beta 2 & 3, I was able to get the card working very quickly.
The USB from the PCIe card, is hooked up to my USB 2.0 Hub. So far that is the best place for it as my USB 2.0 Hub is seen right away. I am not good at soldering so I thought, get a Lenovo card with Intel Wireless, get its open intel wireless source bluetooth driver and grab the Bluetool fix up kext as instructed and Bam! Bluetooth worked on the first try.
This setup worked so well, I decided to remove my BCM card completely and reboots via B2 and B3 seem to be more stable/successful. B2 also got handoff to work. Do not have it on B3 yet.
And what is strange is the Card works perfectly on Monterey but the card does not get a MAC address on Big Sur. I may be able to get the Broadcom card to live on BigSur and the Lenovo Card to live on Monterey with USB Mapping as needed.

9-pin to USB-A. The Lenovo card is a 11-pin, but the 9pin adapter works. A 5-pin should work but the wiring is all mixed up. I had a 5 pin and a 9 pin and could not get an 11 pin adapter, so just skip the 5 pin.

I got this idea from the Broadcom mods, but I felt this was easier and safer and can probably keep my Broadcom card as is for Big Sur and use this new card for Monterey.
the hardest part of this madness is the super tiny antenna prongs.
Kext's used with release links:
My Lenovo Intel Wireless combo 802.11ac/BT4LE card 13 USD off eBay works with just three kext's AirportItlwm.kext 2.0.0 (Monterey) and IntelBluetoothFirmware.kext v1.1.3, BlueToolFixup.kext v2.6.0.
p.s.
After getting Monterey working, I was able to get Big Sur 11.2.3 BT and WiFi working with the same card and meshing with a combination of Apple's drivers and the Open Source Firmware via Open Core.
Really happy with the mod. I am getting a newer Lenovo WiFi/BT4.2 card for a 2009 4,1 that I am getting soon.
