thought about this too(not installing the rom just stripping out whats referanced)... I looked at the reg post in the 6800 forum... there are three DLL's listed... GpsDaemonService.dll, GPSID_QCT.dll, VIRSER_GPS.dll
There are only a few keys that i think could be an issue including these three:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\VirtCOM_GPS1]
"DevConfig"=hex:20,00,00,00,05,00,00,00,10,01, 00,0 0,00,4B,00,00,00,00,08,00,00,00,00,\
00,00
[HKEY_LOCAL_MACHINE\Drivers\Active\36]
"BusName"="BuiltInPhase1_0_8_0"
[HKEY_LOCAL_MACHINE\Drivers\Active\59]
"BusName"="BuiltInPhase1_0_53_0"
Im trying to get the dll's and hack my registry... Also th titan needed to flash the radio(i think) so I have no idea what changed there... But the origianl radio for the 6700 allowed gps.. I tried to find it but someone told me to just give up on GPS with the 6700... anyway I found these pdf that might be useful for all the devices that us the gpsOne chips...
