I'm not using a shared libgcc. It's just freezing after the freeing of  
the initrd memory about the time it should be booting up init. I guess  
my next step is to start throwing in some printk's to see exactly  
where it's dying.

Of course, I can't get a 2.6.23 kernel to even boot at all, but that  
may be the same toolchain issues. My kernel seems to be  
working ok -- that was built with my gcc 4.0.4 based toolchain, the  
only version I've been able to get successful boots from.
