Subject: CONFIG_NO_BOOTMEM woes, 2.6.34-rc1

With CONFIG_NO_BOOTMEM=y, I get:

kobject '' (c252bfdc): tried to add an uninitialized object, something 
is seriously wrong.
Pid: 1, comm: swapper Not tainted 2.6.34-rc1 #121

WARNING: at lib/kobject.c:595 kobject_put+0x27/0x3c()

a bit after which the kernel dies.  Inspection of memmap_init() and 
related code appears to call kobject_init() correctly.

With CONFIG_NO_BOOTMEM, the kernel hangs in early boot before displaying 
anything.

2.6.34-rc1, i386 (x86_64 works fine).
