Alright, I can confirm that I got landscape view working in google maps for the 28005 m2.5 Nov.27 Rom! Had a lil cab I knew would come in handy one of these days. Do the usual flash dance, then install the first cab below, followed by the second. It was probably all of the second cab but the first makes the taskbars disappear in the photo and music tabs in sense. The second program you have to set up the exceptions. Basically do what it is the program is telling you to do, you can't go wrong! I did all of this within five mins of a fresh install and it works!!
See for ya self
I hope I was helpful.
This program may also add rotation support for other programs...Thank me if it works for you.
