if you want your sdcard clean-lembed, so add these modules to a sub directory then change the path in the mount commands to that dir. In my case I did move all modules included build.prop to /sdcard/mods then add these lines to froyo.user.conf:
Code:
mount --bind /sdcard/mods/libGLES_qcom.so /system/lib/egl/libGLES_qcom.so
mount --bind /sdcard/mods/gralloc.msm7k.so /system/lib/egl/gralloc.msm7k.so
mount --bind /sdcard/mods/build.prop /system/build.prop
