Are you sure that the native resolution on your iBook is 800x600 and not 1024x768?
The last iBooks with a native 800x600 resolution were the ones from the "iBook (FireWire)" series (with 366-466Mhz G3s), which was introduced in 2000. Looking at the specs it seems you would not be able to run OS X at a decent speed on these machines. So just to be sure, go to System Preferences->Displays and check what the maximum resolution of your iBook is.
If your max resolution is indeed 800x600, you will have to wait a few more days until I post a new CVS binary. In current CVS code, this issue
is fixed.

Just a general remark at the end:
Please don't start three threads about the same issue. All what this does is to make the forum more confusing, it's not gonna give you your answers faster. Some people might not even reply to your question because they think you are spamming.
I've already deleted the thread that you created in the general help section. The thread in the french forum I left alone because somebody had already replied to it.
So no more cross-posting, ok?
