Optimization team update (11/23 ~ 11/29)

GTK support seems mildly improved in the testing release, but I'm
still having big troubles with it. Note, that relatively simple GTK
apps, such as TangoGPS work without issue.

We're running a complex GTK app:  http://gvsigmobileonopenmoko.wordpress.com/

It works perfectly on 2007.2, but on 2008.x releases it suffers from
multiple problems; layouting and stability seem to the big ones. It is
improved when running on the latest testing release, but still not up
to the standard of GTK applications on 2007.2.

We were promised that we wouldn't need to worry about Openmoko moving
away from GTK as the latest releases would still run GTK applications.
However performance is clearly below an acceptable level.

I will be filing bugs ASAP and would be very interested in hearing
comments from others. If anyone would like a copy of the gvSIG Mobile
ipk for testing, please let me know.

> Upgrade howto:
> From Om2008.9 it's recommanded to upgrade with the following steps:
> sed -i -e 's%Om2008.8%testing%' /etc/opkg/*.conf
> /etc/init.d/xserver-nodm stop
> screen -DR
> opkg update
> opkg -force-overwrite upgrade
> # (please ans Y to all questions)
> # (the sshd (dropbear) will restart, so you need to reconnect and do
> # 'screen -DR' again)
> opkg upgrade
> shutdown -r now
> To get the fastest boot time you also need to remove the following
> packages:
> opkg remove task-base-nfs task-base-smbfs task-base-bluetooth \
> task-base-usbgadget avahi-daemon avahi-autoipd blueprobe \
> usb-gadget-mode portmap exquisite exquisite-theme-freerunner \
> exquisite-themes
> Known issues:
> * GTK redraw problem
> * some obsolete kernel modules still left in system
> * must remove 'ro' in kernel boot parameter if you use sd boot.
> * will purge your incompatible e config, so you might need to set
>  stuffs like suspend time again.

> Team update:
> Tick helped to put his touchscreen improvement into stable-tracking,
