   * The in-kernel sources. If you look under drivers/staging/rt2870/, you'll find a slightly cleaned-up version of ralink's driver. It requires you to enable “STAGING” drivers when configuring the kernel.
-  * Finally, the rt2x00 drivers are in the mainline kernel, under drivers/net/wireless/rt2x00, but these report only testing/development support for the 3070.
+  * Finally, the rt2x00 drivers are in the mainline kernel, under drivers/net/wireless/rt2x00, but these report only testing/development support for the 3070. In fact it works decently and is the best option. It additionally allows to use hostapd (AP mode) and and has monitor/injection support. The main limitation is that it can't have a "managed" and an "ap" interfaces active simultaneously.
+==== Supplemental Chips ====
+There are several supplemental ICs connected to the Tegra 250 main processor via various buses. The following lists some of them:

+==== Mobile broadband ====
+The 3G model contains an Ericsson F3307 Mobile Broadband Module. With the provided kernel sources, this presents itself as /dev/ttyACM{0,1,2} as well as a cdc network device "usb0" (''wwan0'' in recent kernels). Excerpt from dmesg:
