[ltp] T60 and ACPI and hdaps

[Jeff Grafton]

If you do figure out what fixes are necessary to get suspend working, I 
would be very interested in hearing this - feel free to reply to me 
personally if you don't want to spam the list.

As for the HDAPS, I'll echo the others on this one - the reason it 
probably wasn't working for you (even when adding the model string) is 
that the manufacturer string has changed to "LENOVO" instead of "IBM" as 
well.
