laptop-mode causing kernel hangs in Hoary?

[copperfish]

still a problem for me - thinkpad R40 (pretty much the same hardware as
a T40/42)



only on battery - machine just hangs with lots of hard disk activity,
but is completely unresponsive....



got the buttons working fine using a standard debian tpb package (after
reading somewhere that the ubuntu package was borked)  everything now
works, suspend, hibernate, modem, wireless etc.  just this crash issue
(which to be fair I had with Fedora too)



ho hum.....anyone any closer to a solution for this?
