I've now updated to xf86-video-intel 2.1.99 and that seems to work fine
with vbe_post and vbemode_restore and it breaks with vbestate_restore,
just like Mads Villadsen has reported.

So I'm fine with a change to your original proposal:

  <merge key="power_management.quirk.vbe_post" type="bool">true</merge>
  <merge key="power_management.quirk.vbemode_restore"
type="bool">true</merge>
