Surprise, surprise. I dropped -DMODVERSIONS and it
still works. I went down to 

CC = gcc
OPTIONSCOMMON = -D__KERNEL__ -DMODULE -Wall
-Wstrict-prototypes -O2 -I/usr/src/linux/include
-include /usr/src/linux/include/linux/modversions.h
OPTIONSTULIP = $(OPTIONSCOMMON) 
OPTIONSPCISN = $(OPTIONSCOMMON) 
all:
        $(CC) $(OPTIONSTULIP) -c tulip.c
        $(CC) $(OPTIONSPCISN) -c pci-scan.c
clean:
        rm -f *~ pci-scan.o tulip.o

with a still working prototype. Interestingly, the
missing symbol errors appear when I drop the last
option in OPTIONSCOMMON. It seems that 2.4 likes
modversion.h be processed before anything.

Again, -DMODVERSIONS can be dropped. We have to figure
out if we can drop -include <linux/modversions.h>.
Note that this shows up when I compile my kernel so
maybe it has to be there for some reason.

There are however other problems with 2.4 kernels.
mii-diag simply gives:
Using the default interface 'eth0'.
SIOCGMIIPHY on eth0 failed: Operation not supported
This did not happen with 2.2. I did not pass any
options for loading pci-scan.o and tulip.o in neither
of the kernel versions.

The other problem is that I get in my syslog lots of
kernel: Warning: kfree_skb on hard IRQ d0874b14
