--- Comment #54 from austin.hoppe7 at live.com ---
Awesome. To spell it out a little more explicitly, here is what I did (Arch
x86_64 3.14-mainline) to have this apparently accomplished automatically from
now on:

sudo su

echo 'ADD_PARAMETERS="--quirk-test --quirk-s3-bios"' >>
/etc/pm/config.d/00-fix_dv6z_suspend_screen

pm-suspend --quirk-test --quirk-s3-bios --store-quirks-as-lkw

Which should save the quirks, perhaps with some redundancy. Checking the
contents of the (new)

/etc/pm/last_known_working.quirkdb

file should show the matches made against your particular system, especially
e.g. hardware and firmware details. I guess these could be patched into (for my
HP at least)

/usr/lib/pm-utils/video-quirks/20-video-quirk-pm-hp.quirkdb

with some of the returned information, given that this file is supposed to have
a fairly up-to-date {white,black,broken}-list.

Obviously follow this only at your own risk, etc. I have no idea how this would
work when it comes to fglrx, or even how stable it is against
kernel/pm/upower/whatever updates. Here are some more good references for
information:
