I believe this resource may help you the most. Install locations should be done through the AndroidManifest.xml file and I believe it was introduced with Android 2.2 (froyo) meaning older phone (2.1 and below) cannot install apps to the SD card.

Resource says:

The ability for your application to
install on the external storage is a
feature available only on devices
running API Level 8 (Android 2.2) or
greater

Bitt Fault, with his app SDWatch is able to show the user the app setting page. I’m not sure if I’m reading it completely right, but you may able to do it with this code snippet from NotificationClicked.java

Intent oi = new Intent(Intent.ACTION_VIEW);
oi.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails");
oi.putExtra("pkg", pkg);
oi.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(oi);

I’m having a little trouble figuring out what the String pkg is exactly though.
