Actually the upstream kernel works. I was trying with a minimalistic system (kernel 3.3 + busybox, both build from upstream sources) and even the framebuffer seemed to work fine.

If your board hangs on boot, you may get more error messages to
figure out what the problem is if you enable:

 CONFIG_DEBUG_KERNEL
 CONFIG_DEBUG_LL
 CONFIG_EARLY_PRINTK

If it makes any difference, my environment is:

  I use omap2plus_defconfig as my base config, then enable a few
  extra items so I'll have ethernet:

    CONFIG_USB_EHCI_HCD
    CONFIG_USB_NET_SMSC95XX

  and I enable real time because that is what I am working on:

    CONFIG_PREEMPT_RT_FULL

  My root file system is NFS mounted from a server.

Don't know if this helps or tells anything new. (I only compiled the kernel on my own once, it was Caldera OpenLinux 2.3, go figure ;). So I'm not well versed on kernel switching, much less compiling and even less hacking :).
