There seems to be a mismatch between what's in wireless-regdb and the actual regulations in Malaysia. See http://www.skmm.gov.my/skmmgovmy/files/attachments/WiFi%20Guideline-Final%20V.pdf Direct clarification might be needed from the Regulatory Division of the Malaysian Communications and Multimedia Commission. Contact information can be found in the PDF.
