I got everything in place to do a working hot-add with 2.6.17-mm1 and I
ran into another trouble spot.  

I added the memory just fine(new device is sysfs) but when I went to on-
line them in sysfs I tripped over the little section of code this patch
comments out.  I was get device not ready messages on my console and the
comment printed in my kernel log.   

  With hacked acpi drivers outside of -mm I don't run into the problem
so I think something is a little off in -mm. 

  The code is expecting the added but not on-lined code to be marked
reserved. This isn't happening for my ACPI hot-add on x86_64. I am not
sure who in this call path needs to reserve the pages or if the check
for reserve is a valid with this new hot-add code.    

Any ideas?
