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
