I have tried my old Trancend 64Mb, RamStar 521Mb and NCP 64Mb cards. My old cards returned right id[ATA_ID_CONFIG] = 0x848A. But I have to use Kingston CF Card 1Gb 2008. ata_id_is_cfa() returns 0 for it and id[ATA_ID_MAJOR_VER] = 0 id[ATA_ID_CONFIG] = 0x044A I have only CF+ specification revision 2.0, but I've found in wiki: (http://en.wikipedia.org/wiki/CompactFlash#CF.2B_specification_revisions) "... While the current revision 4.1 from 2004 works only in ATA mode, ..." So I have reached an impasse.
