That's just about completely incorrect.
More accurately, it defaults to:
1) whatever lspci says the first VGA compatible device is, if lspci is
available, returns information, and (if you have more than one video
card or if you're on a PowerPC);
2) "1", if you're on an SGI Indigo2 machine;
3) blank, if neither of the above apply
Let's look at the code, shall we?

I think you're proceeding from an invalid assumption; namely that
"PCI:0:1:0" is some sort of hard-coded default.

The debconf template explains the format, and cautions about the
difference between decimal and hexadecimal.
I am unwilling to change the format of the BusID parameter that the
XFree86 X server accepts. To do would render people's XF86Config-4
files incompatible between distributions.
If you have suggestions for how the following can be improved, please
offer them.
Template: xserver-xfree86/config/device/bus_id
Type: string
_Description: Please enter the video card's bus identifier.
Users of PowerPC machines, and users of any computer with multiple video
devices, should specify the BusID of the video card in the format:
.
PCI:nn:nn:nn
.
(where each nn is a decimal number referring to the card's bus, device, and
function number, respectively).
.
For users of multi-head setups, this option will configure only one of the
heads. Further configuration will have to be done manually in the X server
configuration file, /etc/X11/XF86Config-4.
.
Users of SGI Indigo2 XL machines should specify simply "1" here.
.
You may wish to use the "lspci" command to determine the bus location of your
PCI or AGP video card. Keep in mind that lspci reports the bus, device, and
function numbers in hexadecimal, not decimal.
.
When possible, this question has been pre-answered for you and you should
accept the default unless you know it doesn't work.
.
Users of machines other than PowerPCs or SGI Indigo2 XLs with only one video
card should leave this entry blank.
Does anybody actually read the template descriptions I write? You're
from France -- is the French translation badly out of date?
