It is not a modutils problem, it is a fixed restriction on the size of
the uname() fields, modutils just uses what uname -r gives it.

         struct utsname {
                      char sysname[SYS_NMLN];
                      char nodename[SYS_NMLN];
                      char release[SYS_NMLN];
                      char version[SYS_NMLN];
                      char machine[SYS_NMLN];
                      char domainname[SYS_NMLN];
                      };

SYS_NMLN maps to _UTSNAME_LENGTH.
/* Length of the entries in `struct utsname' is 65.  */
#define _UTSNAME_LENGTH 65

Like you said, don't do that :).
