Great testing. The Fedora Live CD 11 contains a very recent kernel
and should recognize all known (at least to me) ITE-chips.

Not only lspci is important, also the output of dmesg (grep for tty)
and the file /proc/ioports.

Compared this to one of the ITE-chips here. I'm not convinced this is
a chip by ITE. Can you tell me the exact type of it887x (x=...)?

This rough patch was available for kernel-2.4. As nobody But ITE could
provide us (Wincor-Nixdorf) with drivers for kernel-2.6. I was assigned
to implement the serial-part of the driver in 8250_pci.c.

Hope that helps,
Niels

Re: Regarding PATCH for ITE887x Serial

[Christopher]

Hi Niels,

I don't really know why but the output of dmesg only shows my oboard 
serial. I have looked all over the dmesg and i cannot find the device 
even at an unknown state
I have even checked dmesg log for the matter.

These are discovered for the onboard serial ports.
kernel: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
kernel: serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
kernel: 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
kernel: 00:0d: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

I will try and remove the card to read what it says exactly on the chip 
and update the email. Its definitely ITE but i will give u exactly what 
it says on chip.
