Rotate Display while docked - is this possible?

[rockhard1972]

Hi,

I've got a Minidock II for my Thinkpad with Radeon 9000 and would like to hook it up to an external TFT via the minidock.
Would it be possible to have my primary display on the Thinkpad set as "Landscape" and then have the secondary display (19" TFT) rotated as "Portrait"?
I seem to remember that ATI offered the option to rotate displays but I cannot find anything in the IBM version of the drivers.
If anyone can point me in the right direction or offer any advice be grateful.

Thanks,

Chris
