Works fine here as well, apart from the errors above.
One thing I've spotted while developing my own work is that when checking the availability of a graphics mode on an iBook or PowerBook is that the returned hertz is always 0 - probably due to the TFT screen used on those. I suspect that Macs connected to CRT monitors don't suffer from this, but I've not had the opportunity to try. Therefore, specifically checking for a refresh rate on a Mac may not work.
