Asus Z71V Suspend & Hibernate issues

Bug Description

On my up-to-date Breezy install, hibernate and suspend-to-ram aren't working.
Both worked with
the install I had before (Hoary with the Breezy kernel packages).

For both hibernate and suspend, it seems to go into the sleep mode fine. It's
resuming where the
problems show up.

On resume from hibernate, it shows the "restoring" text, and then brings up a
blank-but-backlit
screen which ignores keyboard input. The machine doesn't respond to pings.

When resuming from suspend to RAM, the screen ends up blank and not backlit. The
machine doesn't
respond to pings.

In both cases after powering the machine off and rebooting it comes back up fine
after complaining
about journal replays.

With the release of Breezy, I thought I'd check to see if this worked
yet - Apparently not. Here's my results testing hibernate:

Setup = ubuntu breezy default (clean install, except kept /home, at preview
release then let automatically upgrade to breezy final)

Using nvidia drivers.

Menu shut down -> hibernate with default /etc/defaults/acpi-support
    boots up with black & white pattern.
After enabling DOUBLE_CONSOLE_SWITCH, it comes up with blank but backlit
screen.I get the same blank screen on resume when hibernating from a text VT,
reguardless of the setting of DOUBLE_CONSOLE_SWITCH.

In neither case does it respond to keyboard input, including not changing
keyboard LEDs with caps/scroll/numlock.

The Asus Z71V is a Centrino (533mhz fsb) based Asus laptop with PCI express
video (GeForce Go 6600). Hibernate worked beautifully in Hoary.

Based on a post on the forums, I tried disabiling the boot splash feature.
Hibernate & resume now work. Suspend to RAM still seems to be broken.

So... this problem is back in Dapper. Disabling boot splash doesn't help in the least anymore.

It's like every time I upgrade to a new version of Ubuntu I lose a ACPI feature (Suspend worked in Warty).

And when I say "Warty" what I actually meant was "Hoary".

When I boot to the non-backlit blank screen after hibernating, the capslock and numlock keys are able to trigger their LEDs. This is true reguardless of whether I hibernated from X or from a virtual console - since I have capslock-is-control set in Gnome, this indicates that there isn't an X desktop there that I can't see.

This works in the Beta.

Apparently the policy is to have the alpha be horribly broken and have the beta work perfectly. Seems like a perfectly reasonable plan to me.

Both suspend to RAM and hibernate appear to work beautifully in Ubuntu 6.06 Beta.

Text VTs are corrupted after resume (like in Breezy), but I can live with that.
