What about newer kernels .35 , .37, .38-rcX ?

I've not tried to use those.

I think you should try at least .37 to see if bug is not
fixed there by chance. If it is, finding fix for .33
would be easier.

(2) When multi processor mode is enabled
    When SMP option of the kernel is disabled (CONFIG_SMP=m), this 
    panic doesn't occur.

For CONFIG_PREEMPT=n and CONFIG_SMP=n spin locks are compiled out from
kernel, they are simply not needed.

The same goes on CONFIG_PREEMPT=n and CONFIG_SMP=y ?

No, spin locks are wiped out only with both disabled.
