The issue is that the invalid values in the table were never caught because, for some reason, Windows never used them. The bug is that we're not using the same heuristic as Windows. Applying a static list of hardware just results in it being likely that we'll never fix that bug. -- Matthew Garrett | mjg59@srcf.ucam.org
