The "VIA VT8231" is a South Bridge with support for a bunch of
"legacy" ports per:

parm:           init_mode:Initialise mode for VIA VT8231 port (spp, ps2,
epp, ecp or ecpepp) (charp)

Some sound cards use a VT8231.

I wonder if init_mode changes the device ID.

If the driver in Fedora Live works either the vendor tested a different
card, used different driver options, or the driver has changed.   It is
easy
to compare lsmod lists and the pciid.  As usual, ArchLinux has good
documentation: <https://wiki.archlinux.org/index.php/Kernel_module>

To avoid the manual "echo XXX XXX > .../new_id":
