So I got this error notice at bootup with the current -git tree. Everything seems to work despite it, but I thought I'd mention it.
[drm:ironlake_update_pch_refclk] *ERROR* enabling SSC on PCH
This is a Lenovo X1.

Thanks. I've got a patch series that fixes a pile of refclk bugs which is still out for review that should fix this. This error should be harmless, but still..

And what about blanking (black screen) issue reported Sep21? I confirm that disabling the blanking e.g. commenting out /* intel_panel_set_backlight(dev, 0); */ in intel_panel.c is somehow working on EeePC as well as Dell machine.
I guess Linus has stopped using EeePCs ;-)
