@mangeurdenuage Hmmm, for super new hardware like this it would not be because of FSF's understandable stance on firmware.
Specifically, the binary blobs the kernel loads into the WiFi card, GPU, and CPU at boot (iwlwifi for BE211, GuC/HuC for Arc B390, microcode updates for Panther Lake). The drivers themselves are in the libre kernel, but they're useless without the firmware to feed the hardware.
