It is a "VIA VT8231"

parm: io_hi:Base I/O address (ECR) (array of int)
parm: irq:IRQ line (array of charp)
parm: dma:DMA channel (array of charp)
parm: init_mode:Initialise mode for VIA VT8231 port (spp, ps2,
epp, ecp or ecpepp) (charp)
Init_mode looks like something you should investigate.
You might also try booting a Fedora Live USB to duplicate the vendor's
