@kemona_halftau T570? not supported in coreboot yet but that's solvable
please tell me if you find a M.2 wifi card that works well with linux-libre. the only one I'm aware of is the QCNFA222, which has broken 5GHz and spams errors in dmesg unless you disable ASPM (or at least the AzureWave version does, maybe there are others. the mPCIe version of the AR9462 works fine)
(also, I'm not aware of any wifi+bluetooth card where both wifi and bluetooth work with linux-libre)
