Hi, the attached patch removes a duplicate whitelist entry for the "ThinkPad H" and adds the "strange" DMI for the ThinkPad R52 (1847W62). BTW, The strange DMIs for the ThinkPad R52 1846AQG and 1847W62 are fixed in latest BIOS. See http://www.thinkwiki.org/wiki/List_of_DMI_IDs#R_series Best regards, Stephan PS: Please CC me as I'm not subscribed to the list. Thanks!
