I'm running debian squeeze/testing/unstable with Jeremy's 2.6.32.x kernel. The best I got to work is the device showing up under Windows 7, with all resources and whatnot. I've applied the vga-loadbios patch and vBAR-pBAR patch to xen, and the vBAR-pBAR patch to qemu-dm. This behaviour isn't stable though. Sometimes I can log on and then domU crashes with a BSoD (nvlddmkm.sys). Sometimes I can log on and actually do something. But certain operations, like changing display options or checking device manager details cause a BSoD. The NVS 295 is based on a G98, which isn't to dissimilar from Eming's GeForce 8400GS. He only states he used 2.6.30-rc3 with some upstream patches, but not more. Has anyone succeeded in passing thru an nVidia graphics card to a Windows 7 x64 guest? Should I try Windows XP, would that make a difference? regards, Helmut
