suspend resume not working on HP/Compaq nw8440

[Michael Class]

Hello,

Description of problem:
In Fedora 9 (same was true for 8) on my HP nw8440 Laptop suspend to ram does not
work. (more detailed: suspend works, but resume does not!)


Version-Release number of selected component (if applicable):
Fedora 9 i386 with current patchlevel (as of May 16th 2008)


How reproducible:
call: /usr/sbin/pm-suspend as root
Laptop suspends
press power button, laptop starts up again, but display stays blank

Steps to Reproduce:
1. as root: /usr/sbin/pm-suspend
2. wait until laptop is suspended
3. press power-button 
  
Actual results:
Laptop boots up, but display stays blank

Expected results:
Latop boots up, resumes with everything working

Additional info:
The issue is the entry in the following file:
/usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-hp.fdi

<match key="system.hardware.product"
contains_outof="nc2400;nc6120;nc6320;nx7300;nw8440;6710b">
        <merge key="power_management.quirk.vbe_post" type="bool">true</merge>
        <merge key="power_management.quirk.vbemode_restore" type="bool">true</merge>

which sets the two quirks vbe_post and vbemode_restore for the nw8440.

Alt least for my nw8440 this is wrong. My nw8440 suspends and resumes (and btw.
 hiberates) perfectly only if these quirks are NOT set.

For me I have changed the sequence to:
 <match key="system.hardware.product"
contains_outof="nc2400;nc6120;nc6320;nx7300;6710b">
        <merge key="power_management.quirk.vbe_post" type="bool">true</merge>
        <merge key="power_management.quirk.vbemode_restore" type="bool">true</merge>

but I am not sure if this will be correct for all nw8440 in the world.

Please let me know if you need further er information.

Michael
