  If you have source, it doesn't have to be 1MB.  Our limit is 2MB.  The
change was made in the /usr/include/sys/param.h file.  The line
 ..#define CDLIMIT  (1L<<11)    /* for 1mb limit */
was changed to
 ..#define CDLIMIT  (1L<<12)    /* for 2mb limit */

  'Course, this is SysV Rel2 Ver2 source, and the change does require
the building of a new kernel.
