[U-Boot] What linux kernel binary do I use????

Hi All,
I am really REALLY stuck - I don't know what kernel image to use with
bootm (and where to load it and quite a few other things but getting the
right image would be a good start)
Now I _do_ have the go command working (needed a bit of a source tweak).
so I can:
boot > setenv loadaddr 40000
boot > loadb
boot > Ctrl-\ c
C-Kermit>send hello-world.bin
C-Kermit>Ctrl-\ c
boot > go 40000
## Starting application at 0x00040000 ...
Example expects ABI version 6
Actual U-Boot ABI version 6
Hello World
argc = 1
argv[0] = "40000"
argv[1] = "<NULL>"
Hit any key to exit ...
## Application terminated, rc = 0x0
boot >
So, I cloned the linux kernel git repository and built 2.6.33rc5, ran
make xconfig, setup some options and compiled.
I have tried:
linux-2.6/arch/x86/boot/bzImage
linux-2.6/arch/x86/boot/vmlinux.bin
linux-2.6/arch/x86/boot/compressed/vmlinux
I've tried to load these at 0x0, 0x10000, 0x100000
bootm always results in:
Wrong Image Format for bootm command
ERROR: can't get kernel image!
go always results in a General Protection fault
README-i386 details loading at 0x0 and running a straight bootm but this
always gives me 'Wrong Image Format for bootm command'
I just simply do not understand what I need to do and it is really
frustrating that something so simple is so hard to do.
Regards,
Graeme
