As long as the same bug/feature is present in the Debian 5.0.1 packages as
the Ubuntu distribution that has the same problem, quite possibly.

The person that wrote what you read has got the wrong end of the stick.

RandR is the 'Resize and Rotate' extension for X. It can dynamically change
modes and resize the root and child windows accordingly.  Handy for things
like projectors and rotateable displays as the desktop fills the whole
screen (and no more), but X doesn't need to be restarted/reconfigured as it
used to to achieve the same effect.  Maybe the person that wrote what you
read figured that with randr, there's no need to specify multiple modelines
any longer, and so _for their purposes_ xorg.conf is redundant and
over-generalised. xorg.conf is useful for more than just specifying
modelines, though, as you've discovered.

Anyway, the long and short of it is that if you create an xorg.conf, Xorg
will use it. I don't know about Debian but the path to it in FC is

randr isn't really configured as such. It's either loaded as an extension
into Xorg (default) or not.
