That’s good to hear. Do you have concrete numbers?

I believe that’s a design decision in coreboot, that the display can
only be initialized after RAM has been initialized. The vendor firmware
seems to be able to do it beforehand. (If I am wrong, the vendor
firmware is really fast in configuring the memory.)
