System: Red Hat 7.2 (fully updated) running a 2.4.17 kernel.

* Copied 2.4.17/.config to 2.5.4/.config
* Ran `make oldconfig' and `make dep'
* Then:

   # make bzImage
   gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/split-include scripts/split-include.c
   scripts/split-include include/linux/autoconf.h include/config
   gcc -D__KERNEL__ -I/usr/src/linux-2.5.4/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -DKBUILD_BASENAME=main -c -o init/main.o init/main.c
