For reference, the oops below still occurs with 2.6.12-rc4-mm2. I've noticed 
that "/sbin/init: error while loading shared libraries: /sbin/init: Cannot 
allocate version reference table: Cannot allocate Memory" appears on the 
console just before the "Kernel panic".

2.6.12-rc4, 2.6.12-rc3-mm2 and  2.6.12-rc3-mm3 all work with the same root 
filesystem which suggests this is a kernel issue of some sort.
