On my laptop, discover erroneously detects two video cards, one trident and
one s3virge. In reality, there is only one s3virge card. Anyway, this
seems to confuse the xserver-xfree86 .config script, which displays
xserver-xfree86/multiple_possible_x-drivers, but then defaults to "vesa"
rather than one of the drivers that were chosen by discover. I assume this
would affect actual systems with more than one video card as well.
Here is the output with DEBUG_XFREE86_PACKAGE set:

Multiple potential default XFree86 server drivers for your hardware.
Multiple video cards have been detected, and different drivers are required to
support the various devices. It is thus not possible to automatically select a
default XFree86 server driver. Please configure the device that will serve as
your computer's "primary head"; this is generally the video card and monitor to
which the computer displays when it first boots.
At the present time, only a single-headed setup is supported by debconf;
however, the X server configuration files can be edited to support a multi-head
For the X Window System graphical user interface to operate correctly, it is
necessary to select a video card driver for the X server.
Drivers are typically named for the video card or chipset manufacturer, or for a
specific model or family of chipsets.
