Yeah, this is because of a change that was backed out because it was
limiting vmalloc= on non-hughmem kernels to be ~500M instead of ~700M or
so, and we couldn't find any bug related to it or figure out quite why
it was there.  It's back in in the build I did today, and I'm advising
the customers who care to bite the bullet and run hughmem.  So this
should be fixed in tomorrow's tree.
