As a Malaysian user, I am really surprised that http://www.google.com.my/ is only offered in English and Bahasa Melayu. If we would take a look at the demographics taken from the CIA World Factbook, the population is composed of : Malay 50.4%, Chinese 23.7%, Indigenous 11%, Indian 7.1%, others 7.8% (2004 est.) Although it is right that the majority of us do speak English and Bahasa Melayu, the usage of Chinese (simplified) and Indian (tamil) are widespread, and thus, should be offered.
If you were to use the argument that there are not enough potential users or that it does not make economic sense, we just have to simply take a look at http://www.google.ch/, which offers English, Français, Italiano and Rumantsch, although the population speaking Italian and Rumantsch are only 6.5% and 0.5% respectively. I do hope that they add the language options soon.
