I agree, but as I outlined above I see it as a none issue. I am fairly 
sure the old toshiba module checks for the presence of APM before 
loading and if it does not it needs fixing so that it does. The two 
modules are mutually exclusive, and it simplifies life for the user 
space programs if they only need to probe the one device.

A bit of poking shows that it is some sort of 2.6.27 kernel module that 
replaces toshiba_acpi. I will download the kernel sources and look this 
evening. I am astounded that such a change could take place without it 
coming to the attention of anyone on this list. I am also curious as to 
who wrote it.
