Thanks Ray for pointing this out. Looks like the mail ended up in my 
spam folder otherwise.

Apart from that this patch is a really really big NAK. I can't count how 
often I had to reject stuff like this!

Using the page reference for TTM pages is illegal and can lead to struct 
page corruption.

Can you please describe why you need that?

Regards,
Christian.
