Hi Ville,

Thank you for the detailed explanation. i completely misunderstood
the purpose of the noarm/arm split regarding vblank evasion, and
i missed the interaction with the mailbox updates in the legacy
cursor path.

Given the architectural complexity required to safely split this
without disarming pending updates, I will drop this patch for now 
and leave the TODO in place.

Thanks,
George
