As a milestone2 owner, I've been following this project closely the last few weeks.
I spent some time on the bluetooth driver hunt, and here's what I found :
-First of all, I'm pretty sure that the TriQuint TQM679002 is a dead-end.
As we can see, on Habe's post (#5), the TQM stands beetween the buetooth/wifi chip and the antenna. TQM deals with the chip, not the os. No driver required then.
The real chip is the WL1273.
-WL1273 and WL1271 belong to the same product class : Wilink 6.0.
The only difference is 802.11a support for WL1273.
This chip handles Wifi, FM radio, and bluetooth.
I would be very suprised if WL1271 driver didn't fit the 1273 as well
-There is a driver project for WiLink 6.0, on TI's website :
ARM Processor Wireless Connectivity - Texas Instruments Embedded Processors Wiki
ARM Processor Wireless Connectivity Downloads - Texas Instruments Embedded Processors Wiki
There is a driver available for Ti Omap 3530, not 3630, but as whe can see -->here<--, the droid x's omap 3630 is a just a faster die-shrink of the 3530. The driver should fit.
The only concern is the kernel version you want it to run in.
-Another option is to contact Motorola Milestone's and Droid's CM mainainers.
Those two phones use the WL1271 and have no problem with bluetooth.
They very probabily can help if asked :
android.doshaska.net | Nadlabak's little bits and pieces for Motorola Milestone and Android
Koush - Viewing Profile - CyanogenMod Forum
Hope this helps...
Now, get CM on your damn' droidx and start working on milestone2 !
Ps: I'd bet this all-in-one driver can also replace the wifi driver you previously found.
Edit : I just realized that what I've found was in fact what Eulerphi8 digged oud in the wifi thread.
Sadly, it looks like he didn't get enough attention at this time, since wl12xx worked.
