If you remember, Via closed down its chipset division, and NV needs to find a CPU partner it hasn't terminally pissed off.
Not much more to say to it than that. NV can't buy Via (allcaps) for a number of reasons, so this is the only door open for the chipset guys. A close working relationship or partnership makes sense for a lot of reasons, and could greatly benefit both sides. All the rumours of buyout talks for the last week were just rumours, this is what was happening behind closed doors.
