Malaysian visa runs still possible?

yes it should still be 3 months for travellers with European pports, visitor's visa upon arrival. Note that you will need your pport also for travelling to Sarawak, and from Sarawak to Sabah. If you go overland you have to p through Brunei, too, and for this ensure that your pport is not just about the expire. You will most probably be required to fill in the white immigration form for travelling between Sarawak and Sabah if on an overland trip; get them and fill them in before you start queueing, otherwise you have to repeat the whole thing...
