card reader на ноуте. кто подскажет куда копать?

ядро gentoo-source-2.6.20.-r7 (тоже самое на 2.6.19-*)
не работает кардридер ноутбук Acer Aspire 5022 на Turion.
модули к нему грузяться, на вставку SD карты udev как-то реагирует, но устройства не создаёт.
может, кто подскажет куда копать, что курить :-)
система amd64
