That's what the original version of the sixaxis patch for BlueZ (the 
one that shipped only in Fedora for a long while) did.

When you create the BlueZ device setup by plugging in the pad, shove 
the SDP record in the local cache as well.

In the worst case, people will need to remove the device from the 
Bluetooth settings, and plug it back in via USB.
