Good call!  Each kernel-image package in debian, has a matching
kernel-headers package.

That got me almost through the install.  Right now make install only
gets a single unresolved symbol message:
	depmod: *** Unresolved symbols in /lib/modules/2.4.19-686/kernel/drivers/pcmcia/cb_shim.o

I installed the kernel-image-2.4.19-686 package[1] and the matching
kernel-image-2.4.19-686 package[2] (these are the newest 2.4 kernel
packages from debian.  I picked the 2.4.19-2 release from debian
unstable).  The make commands were:
	make -k KERN_INCLUDE=/usr/src/kernel-headers-2.4.19-686/include 
	make -k KERN_INCLUDE=/usr/src/kernel-headers-2.4.19-686/include install

So far I have tried the following approaches to avoid the missing
symbols error message:
 1. Tried not building PCMCIA/cardbus support by using the make
	make -k KERN_INCLUDE=/usr/src/kernel-headers-2.4.19-686/include PCMCIA=/tmp

 2. Tried to move away the driver_ops.h fil the Makefile looks for,
	cd /usr/src/kernel-headers-2.4.19-686/include/
	mv pcmcia pcmcia.disabled

 3. Tried commenting out the stuff that adds cb_shim.o, ie.
	ifeq ($(wildcard $(PCMCIA)/pcmcia/driver_ops.h),"")
	   $(warning The PCMCIA header files could not be found.$(newline)\
	 No CardBus support will be built.)
	#  OFILES += cb_shim.o
	#  CARDBUS= 3c575_cb.o epic_cb.o tulip_cb.o realtek_cb.o
	#  CB_SHIM = cb_shim.o

 4. Tried installing the kernel-pcmcia-modules-2.4.19-686 package[3].

For the last attempt I deinstalled the kernel package, and completely
removed the modules directory for this kernel.

Perhaps attempt 1, 2 or 3 would have worked better if I had
reinstalled the kernel between the attempts?  (The reason I didn't, is
that I have to reboot into 2.2.19, every time I need network access,
and this takes some time)
