Below is a small method that resizes all subviews of a split view  
such that
they have (up to rounding errors) the same height. Works for me on 10.5.

- (void)spaceEvenly:(NSSplitView *)splitView
{
    // get the subviews of the split view
    NSArray *subviews = [splitView subviews];
    unsigned int n = [subviews count];

    // compute the new height of each subview
    float divider = [splitView dividerThickness];
    float height = ([splitView bounds].size.height - (n - 1) *  
divider) / n;

    // adjust the frames of all subviews
    float y = 0;
    NSView *subview;
    NSEnumerator *e = [subviews objectEnumerator];
    while ((subview = [e nextObject]) != nil)
    {
        NSRect frame = [subview frame];
        frame.origin.y = rintf(y);
        frame.size.height = rintf(y + height) - frame.origin.y;
        [subview setFrame:frame];
        y += height + divider;
    }

    // have the AppKit redraw the dividers
    [splitView adjustSubviews];
}
