We are doing what you describe right now. So the current code is broken?

Yes.

How about getting rid of the slabs there and use kmalloc? Kmalloc in mm 
(and therfore hopefully 2.6.24) will convert kmallocs > PAGE_SIZE to page 
allocator calls. Not sure what to do about the 1k and 2k requests though.

The problem is that we must never use kmalloc pages, so we always need
to request a page or more for these.  Better to use get_free_page directly,
that's how I fixed it in XFS a while ago.
