the install path for the kernel modules in the ebuild is: /lib/modules/${KV}/net but, normaly wireless drivers are located at: /lib/modules/${KV}/kernel/drivers/net/wireless/ Reproducible: Always Steps to Reproduce: for me, modprobe cant find the modules when they are in /lib/modules/${KV}/net. after moving them to /lib/modules/${KV}/kernel/drivers/net/wireless/, everything works nice.
External kernel modules should not be installed to /lib/modules/${KV}/kernel/ subdirectories. If they are they will be removed upon every 'make modules_install' in /usr/src/linux'. The ipw2200-0.7 ebuild runs depmod in pkg_postinst() so the kernel module loader should be able to locate the modules... Could you please try running 'depmod -a' after installing the ipw2200 and tell us if that solves it?
