I just found the thread on the VT problems with i830. I've a Radeon R250 in my laptop and have the same problem. With the generic driver and 4.2 from Sarge things were fine. I just get no VT switching with the experimental 4.3 packages, since I started using them (-0pre1v3 IIRC).
I never filed a bug because I was under the impression we weren't to file bugs on experimental packages... Please CC me as I'm not on debian-x. Cheers, -- Pax vobiscum; pax cum omnibus.
