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.
