Somewhere between next-20100602 and next-20100604
something was changed that results in ia64 taking deref
NULL oops in sys_init_module() ...

Freeing unused kernel memory: 1984kB freed
modprobe[1851]: NaT consumption 2216203124768 [1]

Pid: 1851, CPU 2, comm:             modprobe
psr : 0000121008526030 ifs : 8000000000000794 ip  :
[<a0000001000f0f31>]    Not tainted
(2.6.35-rc1-generic-smp-next-20100604)
ip is at sys_init_module+0x131/0x420

At the point of dereference it looks like we were trying
to load a 4-byte data object from offset 552 into the
"struct module *" that wa returned by load_module().
