Module fuse.ko won't load on Gargoyle 1.3.10

[gabrielebellini]

Hello to all.
I'm trying to use Dallas/Maxim 1 wire interface on my Fonera 2100 router with the latest 1.3.10 Gargoyle firmware.
After firmware install, issued opkg update and opkg install owfs which installed also all the dependencies (fuse-utils - 2.8.3-1, kmod-fuse - 2.6.30.10-1, libfuse - 2.8.3-1).
Trying to load module (insmod /lib/modules/2.6.30.10/fuse.ko) failed with insmod: can't insert '/lib/modules/2.6.30.10/fuse.ko': unknown symbol in module, or unknown parameter. Dmesg has those three lines:
fuse: Unknown symbol kmem_cache_alloc_notrace
fuse: Unknown symbol __tracepoint_kmalloc
fuse: Unknown symbol slab_buffer_size
Why does the module won't load? The package is fetched from the official openwrt repository, so everything should be fine... Any ideas would be greatly appreciated... Thanks in advance.
