You can confirm this by looking in the log, or by telinit'ing to
console mode and starting the X server by hand (eg, with startx).
On Debian the log is /var/log/XFree86.0 IIRC.

(It would be nice if wileyc would butt in here.)  I don't think that
is true.  This really ought to be as simple as switching from
1280x1024 to 1024x1280 in the config file.

Modern graphics cards have a protocol to tell the server what they
support I believe, and the monitor tells the card what _it_ supports.
Recent XF86 and Xorg servers allege not to need modelines at all most
of the time.

It ought to be as simple as putting a switch on the horizontal and
vertical wires to change roles.  If this isn't in hardware, somebody
blew it.  Cf SL-Cxxxx Zaurii.
