// These values came from SeisMaCalibrate calibration reports. In general I've
// found the following:
// - All Intel-based SMSs have 250 counts per g, centered on 0, but the
// signs are different (and in one case two axes are swapped)
// - PowerBooks and iBooks all have sensors centered on 0, and reading
// 50-53 steps per gravity (but with differing polarities!)
// - PowerBooks and iBooks of the same model all have the same axis
// polarities
// - PowerBook and iBook access methods are model- and OS version-specific

// So, the sequence of tests is:
// - Try model-specific access methods. Note that the test is for a match
// to the beginning of the model name, e.g. the record with model name
// "MacBook" matches computer models "MacBookPro1,2" and "MacBook1,1" (and ""
// matches any model).
// - If no model-specific record's access fails, then try each
// model-independent access method in order, stopping when one works.
