I've posted a first build of CentOS for the Hikey from 96boards, and a ReadMe with the steps required to get the board going.
http://people.centos.org/jperrin/hikey/
The ReadMe assumes that you've at least skimmed the 'Getting Started' section of the Hikey documentation, but walks through the fastboot commands to load the image.
What I consider the 'blocker' to releasing this image presently is the lack of console output on HDMI. If someone's able to make that go, I will happily mail them some CentOS swag and put their name in the release notes for the image.
I believe this will do it for you. Code provided for their demo units. Its due in the end, to the fact that the board outputs one strict resolution. I can't find any sort of licensing on this tiny bit of code though, but the source is made public, freely available with no warranty is the closest I can find to a license.
#include <fcntl.h>
#include <linux/fb.h>
#include <sys/ioctl.h>
#include <sys/mman.h>
#include <unistd.h>
#include <assert.h>
int main(int argc, char **argv) {
struct fb_fix_screeninfo fixed;
struct fb_var_screeninfo variable;
char *fb;
int line_size, size, buffer_size, i;
int fd = open("/dev/fb0", O_RDWR);
ioctl(fd, FBIOGET_VSCREENINFO, &variable);
variable.xres = 1280;
variable.yres = 720;
variable.xres_virtual = 1280;
variable.yres_virtual = 1440;
variable.bits_per_pixel = 24;
ioctl(fd, FBIOPUT_VSCREENINFO, &variable);
ioctl(fd, FBIOGET_FSCREENINFO, &fixed);
variable.xoffset = 0;
variable.yoffset = 720;
ioctl(fd, FBIOPAN_DISPLAY, &variable);
variable.xoffset = 0;
variable.yoffset = 0;
ioctl(fd, FBIOPAN_DISPLAY, &variable);
close(fd);
return 0;
}

So, I'll blame it (publicly at least) on not having coffee yet this morning. Where did you turn up this bit of code, and what does this get added to?

I found it from one of their people on their forums. I tried to track it down in their github, but hadn't found it yet. Since it has a main function, I assume just compile that bit of code and run it as a executable. They may have written it into a kernel patch versus standalone (after demo) for their hosted image (Debian?), I'll see if I can find out.
