 You should have a (very) basic ArchLinuxArm system now. Log in with "root"/"root" and hack away.
+For increased X11 performance build the opentegra driver according to [[http://ac100.wikispaces.com/opentegra]], you need to install libpthread-stubs from AUR [[https://aur.archlinux.org/packages/libpthread-stubs]] and ''xorg-server-devel'' from pacman.
+First, build the modified libdrm:
+  git clone git://people.freedesktop.org/~tagr/drm
+  cd drm
+  ./autogen.sh --prefix=/usr --disable-intel --disable-nouveau --disable-radeon --disable-vmwgfx --enable-tegra-experimental-api
+  make
+  make install
+Then, build the opentegra driver:
+  git clone git://people.freedesktop.org/~tagr/xf86-video-opentegra
+  cd xf86-video-opentegra
+  ./autogen.sh --prefix=/usr
+  make
+  make install
