I was able to install Google Currents by manually adding the framework from the gapps zip normally used by CM7 and other roms.
I've included a View attachment maps-framework-kfire.zip modified zip (maps-framework-kfire) file with only the files you need. The files are in the folders necessary inside the zip. As we can't flash zips from recovery like other devices yet (that I know of) you'll have to put the files in manually. As this uses google services you probably need to have View attachment GoogleServicesFramework.apk installed already in your /system/apps directory (to do this if you haven't either install the market which will include this step or transfer the GoogleServicesFramework.apk there and chmod to 644 like the others below [do this before you reboot as it will be required])
1. Extract the zip file on your computer
2. Copy the extracted files to your device
3. Copy com.google.android.maps.jar into /system/framework via ADB or Root Explorer
4. Chmod (long hold select file in Root Explorer and select permissions) to 644 (owner read/write, group read, others read)
5. Copy com.google.android.maps.xml to /system/etc/permissions the same way
6. Chmod that file to the same permissions
7. Restart your Fire to allow it to recognize the new framework
8. Install this APK View attachment Google_Currents_1.0.apk
9. Open the app and select your Google account to continue
This should also allow any other apps to install that require this framework.
