The following is free output from a native lpar, SLES8 64-bit system:

             total       used       free     shared    buffers     cached
Mem:       8186328    8140748      45580          0     239356    4173208
-/+ buffers/cache:    3728184    4458144
Swap:     19231808    4762584   14469224

On the occasion when my SAP application gets backed up, it seems like the
swapout is busy.  I would think that if I were swapping, the number of used
buffers/cache (3728184) should be a lot higher because the active pages
should eat into the inactive ones.  But I always seem to have a lot of free
buffers/cache.  Am I thinking about this wrong?  For a 2.6 kernel, it looks
like swappiness might have an effect on this ratio.  Is there anything that
can influence a 2.4 kernel?
