OK, I just confirmed this works. Locks take about 30 seconds but it works!
This is a procedure from xda thanks to

1) if you haven't already, you need to flash your phone to MR1 or MR2 official release. You can find the MR1 for 6900 here

2) install Valhalla .cab file for gpsserver (attached)
3) edit the registry and change the following
3 entries:
* \KHLM\Software\Valhalla Legends\GPSServer\PDEAddress = C3CF657E (REG_DWORD Hex)
* \HKLM\Software\Valhalla Legends\GPSServer\PDEPort = 7788 (REG_DWORD Decimal)
* \HKLM\Software\Valhalla Legends\GPSServer\Mode = 0
Reboot. You must do a soft reset before this will work. Get ready for slower locks and less accuracy, but it does work, and it is good enough for turn by turn in Live Search.
