I cannot get it to compile either:
christoph@...roedinger:~/software/linux/xx/linux-2.6.20-rc6$ make
mm/page_alloc.o
scripts/kconfig/conf -s arch/i386/Kconfig

but I would think that this would fix the compile errors that are my
responsibility (sort of .... patch was against rc6 and not against mm).
More when I track down the above issue:
mm-fixes to ZVC patches
Fix uses of free_pages
