I have one of these systems. I was able to get it to install by playing around in the BIOS, but it was unable to boot afterwards either as a dual-boot or single-boot system. Kris and I need to get together to see what is needed to get the hardware to boot from GRUB. So for now, afaik, this doesn't work yet.
