You were close--instead of -p0, in this case you want -p1, but you also
want to be in the top level linux source directory
(/usr/src/linux-whatever):
cd /usr/src/linux-2.4.19-pre2-ac2
cat ../patch-2.4.19-pre2-ac2 | patch -p1
-p1 means 'strip the first directory off the path, in this case
"linux.19pre2-ac2".
