[Bug 50493] Support removed for previously supported Tulip NIC removed in 2.6.15-25

[Jeff Balderson]

Public bug reported:

Support for the NICs in my system was removed between 2.6.15-23 and
2.6.15-25.

My Devices (via 'lspci -v'):

0000:00:05.0 Ethernet controller: Davicom Semiconductor, Inc. 21x4x DEC-Tulip compatible 10/100 Ethernet (rev 31)
        Flags: bus master, medium devsel, latency 160, IRQ 7591936
        I/O ports at 2010100 [size=256]
        Memory at 000001ff00002000 (32-bit, non-prefetchable) [size=256]
        Expansion ROM at 0000000000100000 [disabled] [size=256K]
        Capabilities: [50] Power Management version 2

0000:00:0c.0 Ethernet controller: Davicom Semiconductor, Inc. 21x4x DEC-Tulip compatible 10/100 Ethernet (rev 31)
        Flags: bus master, medium devsel, latency 160, IRQ 7591232
        I/O ports at 2010000 [size=256]
        [virtual] Memory at 000001ff00000000 (32-bit, non-prefetchable) [size=256]

If you do "modinfo tulip" for the 2.6.15-23 kernel, it includes these two lines:
alias:          pci:v00001282d00009102sv*sd*bc*sc*i*
alias:          pci:v00001282d00009100sv*sd*bc*sc*i*

That's the only difference between the tulip modules in 2.6.15-23 and
2.6.15-25 that I can determine.

cat /proc/bus/pci/devices shows my two ethernet devices as (while booted
into 2.6.15-23):
