Eh?  /usr/src/linux/README says

 - if your kernel is too large for "make zImage", use "make bzImage"
   instead.

/usr/src/linux/Documentation/Changes says

   The boot support in 2.0.x (for arch/i386) has been enhanced so that
it now can load bigger kernels (bzImage) and that the loaders now can
load an initial ramdisk (initrd). For initrd see
Documentation/initrd.txt. For building bigger kernels use one of the
following make targets: bzImage, bzlilo, bzdisk (equivalent to make
targets zImage, zlilo, and zdisk respectively). If you want or need to
use the new features you'll need to upgrade your bootloaders.  Lilo can
be found at ftp://lrcftp.epfl.ch/pub/linux/local/lilo/lilo.19.tar.gz.
LOADLIN is at
ftp://sunsite.unc.edu/pub/Linux/system/Linux-boot/lodlin16.tgz.  If
you're using more unusual loaders like SysLinux or etherboot, the
latest versions are 1.3 and 2.0, respectively.

The bzImage+initrd patch (bzImage is an extension to load kernels
directly
above 1 MB, which allows kernels sizes of up to approximately 2 MB) can
be
found at
ftp://lrcftp.epfl.ch/pub/people/almesber/lilo/bzImage+initrd-1.3.71.patch.gz
and
ftp://elserv.ffm.fgan.de/pub/linux/loadlin-1.6/bzImage+initrd-1.3.71.patch.gz

I don't see anythiong about a lack of bootloader code there.

: If you use lilo or loadlin then you don't want the bzImage but if you
: cat or dd the kernel image to a floppy then you do need the bzImage
: (unless with dd you skip the boot blocks on the floppy of course).

Uh, no.  I've 'cat'ed and 'dd'ed zImage kernels to floppy disks many
times, and they worked fine.  No offset needed with dd either.

Where did you get this info?
