That depends a lot on the embedded controller in your laptop.
Unfortunately, finding the embedded controller chip by software is next
to impossible because almost all embedded controller data sheets are
under NDA or totally unavailable. That's also the biggest reason why
coreboot focuses on desktop, server and embedded boards. Usually none of
those boards need or have an embedded controller, so we can circumvent
the associated headache.

It can work with GRUB2, but I have no idea about BTX loading. Most
bootloaders try to use BIOS interrupt services and for that you need to
load SeaBIOS.
