You have switched from using the original ISA/PCI ne2000 driver to the PCI-only driver when you upgraded. If you kept the same configuration (i.e. same ".config" file) and continued to use the ISA/PCI driver then things would continue to behave exactly as they did before. So, in that respect, pre16 isn't broken.
[ The ne2k-pci driver gets the i/o address from querying the PCI BIOS and ignores any user supplied values, hence the difference]
Since the tulip probe comes before either of the ne driver probes, a simple "ether=0,0,eth1" should work and put the tulip as eth0 and the ne2k as eth1.
In regards to ordering your cards the way you want, you have several options.
1) use modular drivers & "alias ethN drivername" 2) re-order the probe sequence in drivers/net/Space.c 3) add code to the probe in pci drivers that looks like:
if (dev && dev->base_addr && dev->base_addr != pci_ioaddr) { printk("foo.c: skipping foo card at %#x, i/o doesn't " "match user supplied value of %#x\n", pci_ioaddr, dev->base_addr); return -EAGAIN; }
so that your "ether=..." arguments have effect even on PCI cards.
