Actually, maybe it's not graphics at all. Rafael just sent me a pull
request that fixes a "turbo is disabled at boot, but magically enabled
at runtime by firmware" issue.

The 6.10-rc1 kernel would notice that turbo was disabled, and stopped
noticing that it magically got re-enabled.

Pavel, that was with a very different laptop, but who knows... That
would match the "laptop is much slower" thing.

So current -git might be worth checking.
