There is an entry for X200:

<match key="system.hardware.product"
contains_outof="C400;C840;D500;D505;D800;X200">
<merge key="power_management.quirk.vbe_post" type="bool">true</merge>
<merge key="power_management.quirk.vbestate_restore"
type="bool">true</merge>
</match>

lshal | grep quirk
should list them

We currently have a very unfortunate situation wrt. to Intel graphics
cards. According to one of the kernel hackers, mjg59, Intel graphics
drivers no longer need quirks with kernel >= 2.6.26 and will actually
fail to resume if you apply any quirks. That's why we filter out the
quirks in pm-utils.
As it turns out, this strategy does not seem to work for all laptops.
Either way (filtering out or not), we will break resume on certain laptops.

Cheers,
Michael
