Well, a snag. Evidently the newer kernel is not respecting the power management instructions on the boot params, and keeps wanting to lockup. The guy building it for me is working on a work around. If we can't get coreboot to work I may be stuck with an earlier model such as a T420 as my next box. I was really wanting the 32gb ram capacity of the W520...
I consider the qubes model most secure without any blobs or (ak) the hardware vendor bios. I may have to be keep a blob for the video in order to get the W520 working...
We really need a target built system for coreboot/qubes for the best security. It needs to require ZERO blobs for most security.
I'll keep you posted with the results.
