I would imagine many embedded developers have a PCI or PCIe

Can you provide me the names of your parallel port interface cards?
What mode (i.e SPP, ECP, EPP) must be supported for OpenOCD? USB-based
parallel port adapters do not work at all, right?
The parport driver does direct inb/outb on the parallel port (unless
PARPORT_USE_PPDEV is set), so that would exclude USB adapters. The input
signale are attached to the status lines, so a stock uni-directional
standard parallel port without EPP etc. should work.
I currently have one of these:
06:01.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 0 (Uart)
06:01.1 Parallel controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 1 (parallel port)
which also provides 4 high-speed serial ports.
I have used various MOSCHIP (probably MCS9845) based cards in the past.
I have not tested them, but I would expect these to work:
