Yes, that change is needed for building with the 4g/4g split.

This patch is wrong.  Those nodes are managed by devpts.

doh.  I don't even know who to lart for that one!

Could you please boot with "initcall_debug" and then resolve the final
couple of addresses in System.map?  That'll narrow it down.

Heck it works with initcall_debug:

Red Hat Linux release 7.3 (Valhalla)
Kernel 2.6.0-test2-mm5 on an i686

I tried again without initcall_debug and it doesnt: 

Starting migration thread for cpu 7
CPUS done 16
zapping low mappings.

....

What additional info you guys want? 

Full output of both with/without initcall_debug boot messages or?

Odd, odd.

What happens near or around the reported point of failure with
initcall_debug on?

Mmmm. 4/4 split now boots again, but behaves rather oddly. This is with
Nick's AS fix, plus the 4/4 fix Andrew sent me last night, which I presume
is the same as what Bill sent out.

Difficult to tell what's going on exactly. For one, the machine has lost 
it's hostname, for another, it seems to have mounted the root fs readonly. 
End of the bootlog looks like this:

----------------------

EXT2-fs warning (device sda2): ext2_fill_super: mounting ext3 filesystem as ext2

------------------------

Mounting the ext3 root as ext2 is normal (it's hard to un-ext3 it
whilst standing on it). The debug stuff & loss of hostname is not.
Won't accept incoming ssh connections. I can sorta start to log in
on the serial console, but readonly-ness screws it:

If I can grab any more useful info, let me know ...

It comes up normally here; not sure what's going on.
