i've tried working some of the SATA disks like above without luck,
but maybe there's something else i can use to generate even more
i/o?  for example, hdparm -tT would be a good candidate, only these
are showing up as scsi...

nope, it's a 2.4.27 kernel, homerolled using the debian config with one
or two unrelated options changed (needed for RAID or detecting the
controller properly, i forget off-hand)

also, i was inspired to see how the random seed is initially set, and
tried catting some stuff onto /dev/urandom (as is done in the
urandom.sh init script), but still no luck.
