I tried the -mm kernel which has this patch included and it still didn't work, 
nor did pci=assign-busses. I have found out however, that theoriginal owner 
of this laptop, my brother, could not get a card working under windows which 
leads me to believe it is a BIOS/hardware problem. The interesting thing is 
that there seem to be no referances on the web to CardBus problems under 
windows, indeed there is one page that was cached by google where the author 
said he had the same laptop and problem as me however a card did work under 
windows. I would try to install windows and test this, however I do not have 
a spare hard-drive for a laptop.
