The FN-keys for sony vaios are not linked to acpi, but linked to the module sony-laptop. As its developper wrote on his wiki, the Fn-keys are now mapped through HAL (Hardware Abstraction Layer). So it is normal that there is no acpi event at all. Concerning the brigthness support see bug 277589, there is a solution there, for those who can use smartdimmer.
