What is new?
RTL8188 works reliable as the drivers in linux-sunxi were unreliable, the connection was dropping with some routers
AXP152 GPIO support in Linux-sunxi is broken so patches are need to may compile it
USB-Ethernet-AX88772B had some weird issue with XFCE4 which now is fixed in 3.4
sun5i_defconfig do not produce bootable image for A10S
Wifi is about to be fixed now in A13 and A20 images too as suffer the same problem
The last image for the board is available as this torrent here: https://www.olimex.com/wiki/images/b/be/A10S_debian_3_4_GPIO_LAN_USBs_SDs_HDMI_LCD_I2C_100KHz_TS_4G_release_4.torrent
