I don't mind it to be documented somewhere, but I don't see it realistic 
to even try to track all possible kinds of devices. I am trying to make 
the driver as universal as possible and can only hope that it will be 
enough for the most cases. Fortunately it is.

Also, adding special exception for this laptop to the driver is quite 
pointless because while it will pass next 6 months FreeBSD release cycle 
this already not new laptop will be out of market for even more time and 
will be mostly forgotten.
