There is some support for gma 3600/3650 in the latest kernels, not limited to i386. I am using amd64 at the moment. The DRM driver (fbdev uder Xorg) is mostly by Alan Cox and hides under gma500 in kernel settings. Unfortunately, it seems that nobody works on it any longer, last serious changes in April and May.
The driver is not only limited to 2D, but also supports video buffers as small as 8 MB of RAM. I am not able to use 24 bpp color mode on a large, full-HD LCD.
I am not sure if Quantal supports it, haven't tried. I compiled my own from kernel.org sources.
Ladies and gentleman, we have official Linux drivers!
Release notes :-
Not perfect obviously, but it's a start...
The just released driver is for Fedora 16 (32-bit), for desktop Atoms. It's a start, i guess.
What we need to do is to keep this thread on the first page of this forum. A big prominent thread bemoaning lack of drivers can't be good for Intel's image, and that will spur them into action.
for ubuntu 32 bits
That's fantastic, but this driver is probably a backport from Meego and doesn't work on most motherboards - see previous posts in this thread.
I downloaded that version of the powervr driver quietly a week ago and gave it a try. It seems that there are two special libraries needed to support it. One library is part of a proprietary for money java package called Rockit, libosal.so, or the OSAL0 package. Anyone who has Rockit should be able to try the new driver and tell us how it works.
Have you tested the experimental Intel accelerated flash driver yet? In theory, it knows how to find the powervr accelerator chip. If the one you download from Intel is a dud, you can try the flash plugin in Meego dated April 11, 2012. That appears to do acceleration. At least is has the artifacts I remember from using the 1-watt crystalhd card with the Intel D525 desktop board under Linux with the correct Linux driver (not the staging driver for crystalhd).
I owned an Intel D2700MUD board, so I know what I am talking about: It was Cedartrail, but it had no frequency ladder support and ran full tilt all the Time. So, it definitely needed a fan. This Cedartrail board that I am using to write this reply has a working frequency ladder and idles at 798 megacycles per second when not doing full-screen video, meaning, much, much cooler.
This must be a joke: [Phoronix] Intel Winning Over NVIDIA For Linux Enthusiasts
"It seems that among Linux enthusiasts, Intel is gaining market-share thanks to their increasingly powerful integrated graphics backed by a fully open-source driver..."
Lot of uninformed people running around these days. For instance, I have some evidence that the official Intel licensed flash plugin is designed to work with both the powervr and the sandybridge chipsets. Which means you get video acceleration under powervr whether you use fbdev_drv.so or pvr_drv.so as your graphics driver.
Are you sure that linux flash plugin is indeed accelerated on fbdev? Please let us know how to find this evidence and the link to the official accelerated linux flash player from Intel.
