normal operation for opcontrol --ctrx-count=value is to
validate
value and reject runs if value is too low cause it can
freeze
the box due to nmi flood.

2.5/2.4 daemon never validate this value.

2.5 module never validate it.
2.4 validation code has been removed from module
in op_nmi.c Sun Mar 2 2003

this bug is in all oprofile version for 2.5 kernel but only
in 0.5.2cvs for 2.4 module.

work-around: don't pass foolish count value.

Note than oprof_start gui always validate this count,
starting oprofile through oprof_start is safe.

Will be fixed in cvs soon.

regards,
Phil
