Kernel version comparison which should return true for > 2.6.6 returns false for major versions greater than 3 (it also returns true for =2.6.6, contrary to the comment).

This is caused by the following test logic starting at line 196:

    [ ${KV_MAJOR} -eq 3 ] && return 0
    [ ${KV_MAJOR} -eq 2 -a ${KV_MINOR} -gt 5 -a ${KV_PATCH} -gt 5 ] && \
        return 0 || return 1

Changing line 196-198 to read the following fixes the logic to compare greater than or equal to 3 and makes the version comparison match the comment:

    [ ${KV_MAJOR} -ge 3 ] && return 0
    [ ${KV_MAJOR} -eq 2 -a ${KV_MINOR} -ge 6 -a ${KV_PATCH} -gt 6 ] && \
        return 0 || return 1
