If my guess is right, this quick fix might work. Can you please test it, as my a500 decided to have its scsi controller die in the middle of this...
(Proper fix is probably to bring fpu bringup into head.S, since it will be necessary for any printk with CONFIG_PRINTK_TIME on. (Or bring back my use embedded libgcc patch, which was buggy on 32-bit. :\ ))
