Subject: 2.6.23-git10 make bzImage problem

When booted, it complains that kernel size is too big, but size OK for a
bzImage, not for zImage as is returned by the file command, -git9 was
OK, x86_64 SMP kernel on two 64x2 boxes.
I shall supplymy .config if needed, but they are the same as for -git9.

# l arch/x86/boot/bzImage
-rw-r--r-- 1 root root 1761496 2007-10-16 22:45 arch/x86/boot/bzImage

# file arch/x86_64/boot/bzImage
arch/x86_64/boot/bzImage: symbolic link to
`/usr/src/linux-2.6.23-git10/arch/x86/boot/bzImage'

# file arch/x86/boot/bzImage
arch/x86/boot/bzImage: Linux/x86 Kernel, Setup Version 0x206, zImage,
RO-rootFS, root_dev 0x801, swap_dev 0x1, Prompt for Videomode
