Can't get 7248 PreP boot disk working in 2.6

Running an IDE disk and booting off floppy (cheap dual boot, can use the
hard drive to boot AIX this way).

I've never had trouble making a boot disk for 2.4.x kernels. Using the
current bitkeeper 2.4 and 2.6 however, the 2.4 works fine and the 2.6
reads a few sectors and goes to the System Maint disk insert dialog.
Tried different floppies, etc.

To make these I do a make zImage then dd the resulting
zImage.prep to a floppy.

I know there is some odd kernel size limitation which is less than the
actual size of the floppy but that isn't the problem.

# ls -l  bk*/arch/ppc/boot/images/zImage.prep
-rwxr-xr-x    1 root     nogroup   1210629 Mar 16 11:11 bk24/arch/ppc/boot/images/zImage.prep
-rwxr-xr-x    1 root     nogroup   1028225 Mar 16 16:43 bk26/arch/ppc/boot/images/zImage.prep

The 2.4 image is actually larger than the 2.6 image (more stuff in modules
in the 2.6 compile).

# file bk*/arch/ppc/boot/images/zImage.prep
bk24/arch/ppc/boot/images/zImage.prep: x86 boot sector
bk26/arch/ppc/boot/images/zImage.prep: x86 boot sector

I have 2.6.4 running on some macs, even a 7200 so I'm curious if
anyone has clues about this problem?
