I have a laptop running the PAO kernel, only because from the documentation I had it seemed to be the only way to get support for apm and pccards. Is this not correct? If not then what exactly is the difference between PAO and non-PAO kernels? What are those devices supported by PAO which are not supported by the mainstream kernel? Marko
