OK, step by step guide for my current setup, from a fresh N810 with openssh installed. You'll need the Graphics SDK stuff obviously.

1. Flash this kernel - config at http://stskeeps.subnetmask.net/maemo.org/gl/.config

2. SCP OMAP24xx_MBX_SDK_N8xx/bin/binary_omap2420_linux_debug to /root/binary_omap2420_linux_debug

3. Copy omaplcd.ko and mbxaccess.ko into the same directory. This is the driver from http://gitorious.org/mbx-n8x0/mbx-n8x0-modules along with nobackbuffers.patch to save some DMA memory.

4. Copy *.so from binary_omap2420_linux_debug to /usr/lib and run ldconfig

5. Copy mbxdaemon from binary_omap2420_linux_debug to /usr/bin

6. Put in /etc/powervr.ini:

[default]
WindowSystem=wrapperwsegl.so

and upload http://stskeeps.subnetmask.net/maemo...rapperwsegl.so to /usr/lib

4. Start up the MBX daemon..
Code:
cd /root/binary*debug
insmod mbxaccess.ko
insmod omaplcd.ko
mbxaccess_maj=`grep ""mbx"$" /proc/devices | cut -b1,2,3`
/bin/rm -f /dev/mbx
/bin/mknod /dev/mbx c $mbxaccess_maj 0

disp_maj=`grep "omaplcd$" /proc/devices | cut -b1,2,3`
/bin/rm -f /dev/omaplcd
/bin/mknod /dev/omaplcd c $disp_maj 0
chmod a+rw /dev/mbx /dev/omaplcd
sleep 5
/usr/bin/mbxdaemon &
4. Fix up libXau.0 link:

ln -s /usr/lib/libXau.so.6 /usr/lib/libXau.so.0

5. As user, that is, from your X-Terminal, now:

Code:
cd /root/binary_omap2420_linux_debug
./xegltest &
You should now see spinning triangles with some stalls. In the x-terminal you'll observe a bunch of MBX hardware recovery messages..
