I'm getting 404 errors when trying to install certain packages to get the SGX drivers working on gumstix.  Can someone help me out? I've seen posts here before from Sakoman who has had success / helped others get this working but I've been stuck on this for some time now. 

I built the libraries following the instructions for beagleboard, but when i try to install them on angstrom i run into problems:

Running opkg install /home/root/libgles-omap3_3.00.00.06-r5.1_armv7a.ipk gives the following:

ERROR: Module omaplfb does not exist in /proc/modules
ERROR: Module pvrsrvkm does not exist in /proc/modules

FATAL: Module omaplfb not found.

Try `mknod --help' for more information.

Running opkg install devmem2 gives the following:

opkg update doesn't fix it otherwise I wouldn't be posting this.  Any ideas?
