[ale] Touchpad, ipw2200, USB Camera problems on laptop

[Dow Hurst]

I can update that the touchpad is an ElanTech touch pad.  Very nice and 
probably just needs a configuration of the buttons.  I think the driver 
problem is a ACPI timing issue.  After a Google search of alot of sites 
and lists, a FAQ for touchpad problems revealed that the mouse driver 
can be prevented from getting it's interrupt by the ACPI modules.  If it 
is delayed too long then it will give the type behaviour I am 
experiencing.  I think ACPI problems are the bane of many Linux 
installations now.
