Yeah. I tried this using the SYSROOT environment variable, but I think the versioning is messed up. I'll try to figure out what I did wrong and I'll post back to the list when I find an answer. I think what might have happened is I used the build script and tried to do the make modules_install part in another shell. Since you're setting temporary environment variables in the build script, this probably wouldn't work. Stupid rookie mistake.

Yeah. I'm not trying to make things difficult for myself. I just wanted g_ether as a module so I could use the freerunner as a usb flash drive, which requires removing the g_ether module.

Yeah. I think I've already taken up enough of your time with dumb questions. I'd rather you spend it writing kernel patches.
