I don't understand your concern. For instance look at your new implementation

void WINAPI RtlWakeConditionVariable( RTL_CONDITION_VARIABLE *variable )
 {
     if (interlocked_dec_if_nonzero( (int *)&variable->Ptr ))
-        NtReleaseKeyedEvent( keyed_event, &variable->Ptr, FALSE, NULL );
+    {
+        NTSTATUS ret;
+        if ((ret = fast_wake( variable, 1 )) == STATUS_NOT_IMPLEMENTED)
+            NtReleaseKeyedEvent( keyed_event, &variable->Ptr, FALSE, NULL );
+    }
 }

Why not move fast_wake() call into the NtReleaseKeyedEvent() implementation?
