Ok!  That boots on the tiger_defconfig.

Some stuff is weird in the dmesg output though.  You report about
twice as many pages in each zone, but then the total memory is
about right.  Here's the diff of my regular kernel (got a bunch of
patches post-2.6.17-rc1) against a 2.6.17-rc1 with your patches
applied.  Note also that the Dentry and Inode caches allocated
twice as much space (presumably based on the belief that there
is more memory).  My guess is that you are counting the holes.
