Hi,

Effectively, the kernel argument acpi_osi is the one which make the  
switch work correctly. It isn't linked to eva's module.

And I suppose it's actually an easier (and better) way like the one  
you might have used via the dsdt file (which I tried at the beginning,  
but had exactly the same problem of winxp boot needed for card change).

That kernel parameter is THE current solution which works well (and is  
so easy to use, or not to use).
