[Cooker] problems with sleep mode in IBM T30

[Luis Alves]

using mdk 9.0 IBM Thinkpad T30 worked fine.

But using mdk 9.1 on IBM T30 when it goes to sleep mode, everything 
works fine.

But when it wakes up, some times X just disappears,
and some times the laptop just becames unusable,
and I have to poer off the laptop to be able to get the system working 
again.
