Coreboot on brand new laptops isn't actually coreboot like it used to be, it has been reduced to a pathetic vestige of its former self - simply a shim loader layer that does next to nothing besides get the purism phonies all excited for a "free" firmware laptop.
Could I get some details on this please?
I presume the following: "old" coreboot (in the X60 for example) used self-written code for hardware initalization (RAM setup, PCI config) while modern coreboot uses the vendor code for this, embedded in a coreboot frame?
If this doesn't speed up boot time (like someone mentioned before) at least you would get rid of features like Intel AMT - and you still could get a little speed advantage by starting the boot-loader or even Linux directly out of the flash?
