I heard that the X61 firmeware was actually behind that of the T
series. Possibly the x61 will inherit all the changes that the T
series now has when it gets it's next firmware update.
Thanks for pointing this out though. Until Lenovo releases the next
x61 firmware .. this will be a very interesting situation to deal
with.
Perhaps the adding the kernel paramater as Hernrique had said will
probably be the short term solution for T series, till all this gets
worked out over time.
