So I tried mem=16m on my laptop (stinkpad T21). I made the following
potentially useless observations:

inode_cache 840K 840K 100.00%
dentry_cache 746K 753K 99.07%
ext3_inode_cache 591K 592K 99.84%
size-4096 504K 504K 100.00%

pgd 188K 188K 100.00%
task_struct 100K 108K 92.86%
vm_area_struct 93K 101K 92.28%
blkdev_requests 101K 101K 100.00%
Hmm blkdev_requests looks big. 4 struct requests are allocated for every
queue,
which totals about 600 bytes. What does /sys/block and the
blkdev_requests line
from /proc/slabinfo look like?
