The autoscroll-behavior is located in the UITableViewCONTROLLER functionality. To disable the automatic scrolling I found two ways:
1) use instead of the UITableViewController simply a UIViewController - set the datasource and delegate on your own
2) Override the viewWillAppear-Routine - and DON´T call [super viewWillAppear: animated] With both solution you disable not only the Autoscroll, but also some other nice but not
essential features, that are described in the overview of Apple´s class reference: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewController_Class/Reference/Reference.html
