Comment 16 for bug 28925

Running Ubuntu dapper, with the latest CVS version of
http://webcvs.freedesktop.org/xorg/driver/xf86-video-ati/ installed. The PCI ID
of my graphics card is (1002:)5d4f, which should be supported. The
manufacturer/model is Sapphire's X800 GTO Ultimate 256MB. The motherboard is a
RS482-based ATI board.

With "ati" driver (default after ubuntu's gfx detection), X doesn't start at
all. With "radeon" specified, X starts but only with 640x480 resolution whatever
I do.

This bug's aim would probably to have at least 2D working at higher resolutions,
and also have "ati" driver working correctly, ie. delegating the handling of gfx
to "radeon" driver. I can also get some debug output about eg. some variables at
some point in the driver code, if someone would like to know something more
specific. I've only casually looked at the driver code (and X is quite unknown
to me in other ways too), so I would need some specific points to study to
continue myself.
