Michel,
try running lspci and see what IDE interface you're using/
I'd guess that it's Intel 82801FBM controller.
You might want to CC yourself in on this bug:

I suspect that this is going to affect a whole load of new laptop users
as it seems quite a few laptops are using the Intel chipset in question.
