from /usr/src/linux/README:

 - Do a "make bzImage" to create a compressed kernel image.  If you want
   to make a boot disk (without root filesystem or LILO), insert a floppy
   in your A: drive, and do a "make bzdisk".  It is also possible to do
   "make install" if you have lilo installed to suit the kernel makefiles,
   but you may want to check your particular lilo setup first.

   To do the actual install you have to be root, but none of the normal
   build should require that. Don't take the name of root in vain.

 - In the unlikely event that your system cannot boot bzImage kernels you
   can still compile your kernel as zImage. However, since zImage support
   will be removed at some point in the future in favor of bzImage we
   encourage people having problems with booting bzImage kernels to report
   these, with detailed hardware configuration information, to the
   linux-kernel mailing list and to H. Peter Anvin <hpa+linux AT zytor.com>.

make vmlinux for uncompressed
make  zImage for gzip
make bzImage for bzip2

copy it into /boot from eiher . or ./arch/${ARCH}/boot/, setup lilo, away
you go.

vmlinux should be in /usr/src/linux/vmlinux even with our own linux spell
that does bzipping by default for i386.

Just cast it, and cp /usr/src/linux/vmlinux /boot and then point lilo to
it and run lilo.  See if that makes bootup a lot faster?
