Hi,

I've worked around a few issues that people might be interested in.

1. You can get the latest Acer BIOS 1.20 now which enables a switch
between Hybrid and Discrete graphics on my 4810TG with Radeon graphics.

2. When you switch to discrete graphics I can confirm that the ATI
Catalyst 9.6 drivers work a treat. And the drivers lower the GPU power
consumption and improve heat and battery life under 9.04.

3. There is a bug with the WIFI card on WPA2 security with 11n routers.
I worked around this by disabling 11n support. You do this by setting
param 11n_disable50=1 on the iwlagn kernel driver. Apparently its
fixed properly in the latest kernal but I tried 2.6.30.something and
it didn't do much for me.

4. Resume from standby/hibernate was freezing on me with compiz
enabled. Turn off all visual effects and it works fine.

And the things I'm still waiting on:

1. When I disable the touchpad I need standby/resume to get it working again.
2. Video playback crashes with Catalyst drivers. Apparently this will
be fixed in 9.7.
3. The power management button seems to do nothing for me but I don't
really mind too much.
4. Don't want to upgrade my kernel to get the ahci stuff so still on
ide for now.

Damon.
