OK, maybe this helps, maybe it doesn't...
There is a utility posted
HERE that allows you to rotate all the way around the horn.
Run it once and you're right hand landscaped mode, again and you're upside down portrait (VERY useful for IR keyboards when you don't want to fool with the stand), again and you're left hand lanscaped again and you're back to portrait. It toggles through all so you can assign it to a button and click until you have it where you like it.
The page is in Japanese, so here is what you might need to do...
Go here...
http://www.geocities.co.jp/SiliconVa...upertino/2039/
Copy the URL and go here...
http://babelfish.altavista.com/
paste the URL into the
Translate a Web page box.
Select 'Japenese to English' in the language drop down box and click translate.
The link is far down the page. The middle link under 'Screen Rotate' is the zip file if you don't want to bother translating the page.
Have fun!
