Doing a bit more research (I'm starting to think the IT8871F on the chip is misleading) it looks like that support is for a single parallel multi I/O card (with the other 887x cards being serial/parport PCI cards).
I've just installed a multiport serial card released by an outfit called Syba. This is an 8 port serial-only card with an Octopus style breakout cable. The main chipset on it is an ITE IT8871F.
Well 8250_pci.c mentions IT8871, so it is probably 8250 style in
interface then.
The kernel I'm using has 16 for both the NR_UARTS and RUNTIME_UARTS (these machines generally have a minimum of 4 ports). dmesg doesn't show the kernel as recognizing the card and only ttyS0 and ttyS1 (the two onboard ports) show up on boot.I've got two questions on this: Is there a driver I should try force loading on it (and if so, what options to use)? and is there any useful testing I can do to report back to the LKML on this card?
How many serial ports is your kernel configured to use?
