I can't solve your problem, but I can tell you this
combination does work with chunking on my Linux system:

   - DocBook 4.0 DTD 4.1.2
   - Norman Walsh's XSL stylesheets for HTML, v1.25
   - Xalan 1.2.2 with Xerces 1.2.2 (JDK v1.2.2_01)
   - java version "1.2.2"
     Classic VM (build 1.2.2-L, green threads, nojit)
   - Caldera Linux

I just downloaded the latest Xalan-J (xalan-j_1_2_2.tar.gz)
package, unpacked it, and ran this script with success:

#!/bin/sh
XALAN=/home/bobs/xalan-j_1_2_2
DBXSL=/home/bobs/docbookxsl.125
INPUT=$DBXSL/test/book.xml
OUTPUT=/tmp/book.html
STYLESHEET=chunk.xsl

CLASSPATH=$XALAN/xerces.jar:$XALAN/xalan.jar:$XALAN/bsf.jar
export CLASSPATH

java org.apache.xalan.xslt.Process \
       -in $INPUT  \
       -xsl file://$DBXSL/html/$STYLESHEET \
       -out $OUTPUT

So I think Norm and Xalan did finally resolve the xsl:fallback
problem.

And, yes, Xalan is slow to parse the Docbook stylesheets.
They are big!
