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 :).
