Subject: Fix Framework Laptop display flashing white after a while

This seems to happen randomly, usually after a fair bit of use, though more
frequently if I'm on a Jitsi call after about 30m-1h. Perhaps some video
memory corruption. Framework community posts seem to indicate the kernel
parameter in this commit should fix it.
