I'm afraid I've done something in the intervening months that is interfering
with the reproducability of my crashes now! ;)

So here's the situation.

I've reinstalled laptop-mode and laptop-mode-tools; run "sudo
/etc/init.d/laptop-mode start"; verified that "cat /proc/sys/vm/laptop_mode" is
giving me "2", when on battery, indicating that it's active; but I now get no
crashes.

However, if I *manually* run "hdparm -B 1 /dev/hda", on ac or battery, it hangs
shortly afterwards, as before.

So I can confirm that "hdparm -B 1" does indeed cause crashes, but I'm having
trouble getting laptop-mode itself to be linked to that in my setup.  Perhaps
something about how I previously disabled laptop-mode is still causing parts of
the scripts be disabled.

FWIW, I'm using APM, not ACPI -- in my experience, and according to reports on
the linux-thinkpad list, APM works better on this hardware once it's been set
up, so I haven't switched yet.
