Yes, that affects the order of PCI devices on the global list when
you have multiple PCI buses present.  This machine has only one PCI
bus, so is not affected by this issue.

Note that I haven't been running 2.5 kernels on NetWinders until recently,
so I couldn't say when it changed.  A wild stab in the dark, I'd think
maybe the init ordering changed:

2.5.69 (System.map):

c0023ba4 t __initcall_ne2k_pci_init
c0023ba8 t __initcall_pcnet32_init_module
c0023bac t __initcall_eepro100_init_module
c0023bb0 t __initcall_tulip_init

2.4.19 (System.map):

c004ddd4 ? __initcall_tulip_init
c004ddd8 ? __initcall_vortex_init
c004dddc ? __initcall_ne2k_pci_init

2.2.18 (drivers/net/Space.c):

#ifdef CONFIG_NE2K_PCI
        {ne2k_pci_probe, 0},
#endif
#ifdef CONFIG_PCNET32
        {pcnet32_probe, 0},
#endif
#ifdef CONFIG_EEXPRESS_PRO100   /* Intel EtherExpress Pro/100 */
        {eepro100_probe, 0},
#endif
#ifdef CONFIG_LANMEDIA          /* Lanmedia must be before Tulip */
        {lmc_probe_fake, 0},
#endif
#if defined(CONFIG_DEC_ELCP) || defined(CONFIG_DEC_ELCP_OLD)
        {tulip_probe, 0},
#endif
