The Reg says Intel's mobile chipsets will soon be able to support NVIDIA's SLI technology.
Today's rumour suggests SLI will only work with mobile Core 2 Duo-based systems. The implication is that that's the current 945G chipset series, the core logic launched with last January's 'Napa' Centrino refresh. However, it's known that 'Santa Rosa', the next generation of Centrino is due Q2 2007, and it may be that product's chipset, codenamed 'Crestline', that Nvidia is targeting.
Either way, the sources claim Nvidia's announcement will come "soon". Intel has said Core 2 Duo-based notebooks will debut at the end of the month, so if the announcement comes, that's surely when it will take place.
