Tried that but it's hard to tell whether it works because when I resume the
screen is blank. I need to get the quirks back. Ugg..

Up to fedora 11 kernel 2.6.30 I everything worked perfectly. So I have a hard
time believing it's an ACPI issue.
Unfortunately I went from fedora 11 to 14  and didn't validate everything in
between.  I tried to go back to non DRM/KMS but that causes X/KDE to crash.

What's weird is from everything I can tell this is working for Rafael and I
believe I'm using the same exact machine HP Nx6325.

It's really not only this issue. Suspend to ram is pretty much useless as it
hangs more often than not during suspend. Hibernate has the same issue but it
works more often than not.

I was hoping everything was related but from the messages you probably don't
think they are.
