Is the 7150 chip supported?We have not tested the 7150 yet but would expect it to work fine with the 169.12 driver. However it may also not be detected correctly by the AVwizard as its a new chip. So I think you can assume that it will likely work 'out of the box' but there is a small chance that it may need some modest manual tweaks to get it fully working.
Andrew, at least two people have tested the 7150 and just needed the 169.12 driver and UseEvents in the xorg.conf, now in the nightlies.
This chip doesn't really give any advantage over the 6xxx series chips for LMCE 704/710, but AFAIK is no worse.
