With Emacs 21.3 typing C-h v RET line-number-display-limit-width RET
should give you

line-number-display-limit-width's value is 200

*Maximum line width (in characters) for line number display.
If the average length of the lines near point is bigger than this, then the
line number may be omitted from the mode line.

Only if computing the line-number slows down Emacs.  With Emacs 22.1
this variable is customizable.
