I suspect that your module-ini-tools/kmod are built without support for compressed modules. One method to verify this is to run it against ldd : $ ldd /sbin/modprobe linux-vdso.so.1 (0x00007fff918ed000) libkmod.so.2 => /lib64/libkmod.so.2 (0x00007ff9317f1000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ff9315d5000) libc.so.6 => /lib64/libc.so.6 (0x00007ff931214000) liblzma.so.5 => /lib64/liblzma.so.5 (0x00007ff930ff2000) libz.so.1 => /usr/lib64/libz.so.1 (0x00007ff930ddd000) /lib64/ld-linux-x86-64.so.2 (0x00007ff931a06000) As you can see, mine depends on liblzma and libz so it was clearly built with support for both of them.
