I'm using arm-linux-gnueabi-gcc from Ubuntu, version:
gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)

and madde gcc (arm-none-linux-gnueabi-gcc), version:
gcc version 4.2.1

I do not know of other (and special scratchbox old) compiler will work.

fakeroot dpkg-buildpackage
better use: dpkg-buildpackage -b -rfakeroot

Where to get this package?
Workaround: place zImage to the /boot/zImage-2.6.28-omap1
Download package kernel, it contains /boot/zImage*.fiasco
Use flasher-3.5 to unpack fiasco image: flasher-3.5 -F zImage*.fiasco
And then copy unpacked zImage to /boot/zImage-2.6.28-omap1

U-Boot binary is too big (actual size 262580, max size 262144)
Before "objcopy --gap-fill=0xff -O binary", it's size is 985157.
Sounds bad. maybe bad gcc or other u-boot scripts.... Try to use gcc optiomalization for size.

couple warnings:

board.c:393:13: warning: 'omap3_update_aux_cr' defined but not used [-Wunused-function]
Ignore, upstream problems. (You can comment that two functions, they are not needed for our rx51 build).

-> fits.
u-boot.bin should be stripped and not (ELF) wrapped version of u-boot which is bootable by nolo.
