This may not answer the question (epia mini-itx parallel port) but it might
work anyway. In linuxbios V1 in the file
src/superio/via/vt1211/setup_serial.inc
you can add these lines to enable the parallel port. It defaults to 0x378
and IRQ 5 and DMA 2.
	/* Select parallel port */
	OUTPNPADDR($7)
	OUTPNPDATA($1)
	/* set the enable in reg. 0x30 to 00, SPP , 01 = ECP, 02 = EPP */
	OUTPNPADDR($0x30)
	OUTPNPDATA($0)

Put this before this line:
	/* turn off PnP */
	OUTPNPADDR($0xaa)

I just tried this on epia-m and it worked for me, I could see the parallel
port IO register space. YMMV.
