Is There Any Laptop That Supports (Read 'Functions Well') Coreboot Fully?

I am looking for a laptop in which I am planning to flash Coreboot over UEFI. Never was an admirer of UEFI crap. Coreboot looks awesome. AMD chipset preferable, not a fan of Intel CPUs.
If anyone has one in mind, please drop the name/link of Laptop in comment.
