Can you build a 2.6.32 kernel and get it to boot with your toolchain?
That's the first step, make sure you can build and boot the same kernel 
provided by your board, rule out the toolchain.

If you can do that (extract the config from the board supplied kernel, if 
you can), then build from source and boot that.  If that works, do a 
'make oldconfig' with a newer kernel source tree and see if that'll boot.  
Then at least you'll be fairly certain that you have a reasonable 
starting point for your config.
