[ltp] Latest BIOS update on T41 running my fan faster

So the patch defenitely affects the fan action: I tested with DynamicPM
off off and the fan came on almost immedietely. Turning it on and
starting this email and the fan went off!! Thanks Alex :)

So the testing thus far (once again only using xengine and glxgears)
gives me
	DynamiPM on
		best xengine 4398
		best glxgears 1029
	DynamicPM off
		best xengine 7960
		best glxgears 1069

so yes, turning it off restore the full performance, while DRI doesn't
seem to be affected by it.
