Initially the build would crash with an embdebian gcc 4.4 bug so I switched over to the emdebian gcc 4.3 (via alternatives) (I am using Debian Squeeze) and all is well. I end up copying the uImage and a tar of the modules across to my Neo. Once there i copy the uImage to the fat partition and the /boot directory of the second partition (I also do a depmod -a <version>). When I reboot the phone, after the initial goldeco logo screen I end up with a blank screen with a small tux logo in the top left and no log output. Tyhe boot seems to go nowhere and when I connect the Neo using the USB cable to my PC, NetworkManager does not detect a USB ethernet device (no message to that effect in dmesg output either).

You have the right git branches.  I'd probably avoid 3.5 until you have some
success with others as it is mostly like to have odd issues still.

For 3.2 you want "gta04a3_nodebug_defconfig"  for others you want
"gta04_defconfig".

I don't suppose you can connect a serial cable to the console port?

Assuming not, change the "CONFIG_CMDLINE" in .config to have "console=tty0",
then "make oldconfig", make and try that.  It should display console messages
in the screen under the 'tux'.  It won't help if it is crashing very early,
but that is unlikely.
