That is useless, since the reported symptomes do not apply to non-working Haswell. Since the last update of the OS - today, CURRENT 277900, the high res console is gone and has fallen back to the 800x600 pixel. The same with the X11 server's display resolution. I can not use VESA driver on the Lenovo ThinkPad E540 with i5-4200M, since it doesn't startup. I have to use xf86-video-scfb which is a pain in the ass. An alternative is to use Ubuntu on the Lenovo E540 and L540 we purchased.
