AFAIK, there are essentially three "Centrino" chipsets Intel 855GM [1] Intel 855PM [2] Intel 855GME [3]. So 855PM based laptops seem to work, whereas 855GM based laptops apparently don't. So it would be logical to assume it is the difference between these two that causes the problems. Unfortunately I'm not sure whether that brings us any further as it seems that it is the integrated graphics stuff that makes the difference -- or is there more?
