nouveau, the project for creating a free 3D linux driver for nvidia cards, recently got first support for real 3D applications with gallium on some NV4X cards (see Nouveau Companion 36). Today I got it working on a friends machine.

Here you can see an openarena benchmark (also uploaded on youtube). It got 55 fps, which is far away from the nvidia binary driver yet (178 fps), but at least more than my r200 setup (32 fps).

For the brave ones, here's a quick and dirty howto for Gentoo:
a) Get the nouveau overlay with svn co https://svn.hboeck.de/nouveau-overlay and add it to PORTDIR_OVERLAY in make.conf.
b) The nouveau-overlay won't install the nouveau/gallium-branch of mesa. Get my overlay with svn co https://svn.hboeck.de/overlay and also add that to your PORTDIR_OVERLAY (I'll try to contact the nouveau-overlay developer if we can merge this).
b) Add media-libs/mesa, x11-base/x11-drm, x11-libs/libdrm and x11-drivers/xf86-video-nouveau to /etc/portage/package.keywords and merge them.
c) If you've been running the nvidia binary driver, eselect opengl set xorg-x11, change the graphics driver in xorg.conf to nouveau, rmmod nvidia (if you've been running the binary driver), modprobe nouveau and start X.
d) Have fun!

Note: The nouveau developers consider gallium completely unsupported at the moment and don't want to get end-user bugs. If it runs, fine, if not, don't nag them with it.

My laptop (Samsung P35) has an internal card reader (SD and MemoryStick) done by Ricoh. Several other laptops have this device. It's internally connected as a pcmcia-device and shows up as RICOH Bay1Controller on pccardctl ident.

For years now there was no way to get this thing running in linux, which stopped me from doing projects like having a crypto-key on a small SD-Card and insert that on boot. Now, finally someone did the job and reverse engineered the device: sdricohcs

In my first small tests, I could already download some photos from my digital camera card. No problems so far. Now, the only thing I'm really missing with linux on my laptop left is TV-Out (works with ati binary drivers, but they are unstable like hell). I heared some Xorg-devs are already working on it, so maybe I'll soon announce the »nearby 100%« support for Linux on Samsung P30/P35.
