Hi,

I have three DC21143 ethernet cards and with 2.3.99-pre5 all of them are
detected as eth0:

eth0: DC21143 at 0x1080 (PCI bus 0, device 13), h/w address 00:80:48:cd:77:c2,
      and requires IRQ11 (provided by PCI BIOS).

eth0: DC21143 at 0x1400 (PCI bus 0, device 14), h/w address 00:80:48:cd:80:0a,
      and requires IRQ10 (provided by PCI BIOS).

eth0: DC21143 at 0x1480 (PCI bus 0, device 15), h/w address 00:80:48:cd:77:17,
      and requires IRQ15 (provided by PCI BIOS).

This is independent of the setting of the PIIX support in the kernel (I
have PIIX4). The contents of /proc/pci (which shows only PCI device 13)
and entire dmesg is attached.

I can provide more info if necessary - but please write me directly, I am
not on the list.

Best regards,
Lada
