Thinkpad Touchpad no longer works

[Barry Samuels <barry@beenthere.mail1.co.uk>]

I have an IBM Thinkpad R61 running Debian Testing with kernel 2.6.30. 
After a recent system update the touchpad no longer works. The red button 
thing, whatever they call it, embedded in the keyboard and its associated 
buttons all work but the touchpad and its associated buttons don't.

I have tried various xorg.conf configurations and no xorg.conf at all but 
it makes no difference.

I've tried booting from a Knoppix DVD v5.1 with a 2.6.19 kernel and it 
works with that.

Can anyone suggest a reason for this?
