Apologies if this is thread hijacking...but I've got a similarish problem on Lenovo laptops that we have on the todo list to investigate so wanted to jump in with a somewhat related question...

It sets a flag in the EC registers to let the OS know the touchpad is not supposed to be enabled (I only just found out this is how it is supposed to work). I'm not 100% sure the reasons for this - I think it's to do with keeping the trackpoint usable (maybe). So just curious on the comment above - is there a standard way to let user space know to ignore the touchpad or disable it by default? I'm obviously being lazy here as I've been meaning to go and read code but I was flicking thru the mailing list and this caught my eye....and if there's a shortcut to the answer that would be awesome. I've no idea if this is a Lenovo specific issue or more generic - but this thread made me wonder if it's actually a common/standard problem? Mark
