It's capped at the screen refresh rate. Which is 60Hz for the iBook LCD.

If your LCD can't take it you can't.

Despite numerous bug reports and detailed explanations to the relevant people at Apple of exactly why it sucks, Core Graphics reports most (all) LCDs as having a refresh rate of 0 fps (and doesn’t allow vertical retrace synching except that built into OpenGL). The standard work-around is to treat 0 as 60; the “lag” of current LCD technology means that faster refresh rates are pretty pointless anyway.

You can see if this is the case in System Preferences – if the Refresh Rate pop-up menu is greyed out and reads n/a, the refresh rate is being reported as 0. (The interface may be different on pre-Tiger systems.)

On systems other than Mac OS X, the cap will be whatever SDL says the refresh rate is.
