I got some relevant information from System76 on mail and am allowed to leak that here:
We're looking at using the Sandy Bridge IGP, however, support for it in Ubuntu is currently in it's very early infancy. It's something that we hope to offer as soon as it becomes a viable option, but it probably won't be until Ubuntu 11.04 is released, and I don't have any sort of time frame for when it will be available.
I don't think the hardware prevents use of the IGP, however, the BIOS isn't set up for switchable graphics, and changing that would require patching the BIOS. There's still a lot or work on the software side of things before switchable graphics in Ubuntu is a strong possibility, and it would probably require a fundamental reworking of the X Server code. However, if it becomes a viable option, I'm sure we'll take advantage of it.Since shipping alone from US to Canada and then to Germany would cost at least 300€, not to talk about possible warranty issues, I am now stuck to get a machine from some proprietary brand :-/ Or have I missed companies shipping to the EU? (I know ZaReason already, but they are not really attractive to me)
