Hi Toke,

My understanding is that the GPLv2 is ambiguous wrt. patent licensing,
which is unfortunate as it is the current license of this code.

I'll get an official statement from our legal department regarding the
use of the patent in the context of the Linux kernel, hopefully in a 
reasonable timeframe as a few key people are currently on vacations.


Best,
Olivier
