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

[Charles Gillet]

Ok, since you're all dying to know, and because I was going deaf, the 
answer is yes, the newest BIOS is the problem.  I backed off to 3.00, 
leaving the Embedded Controller version up to date, cooked the CPU with 
a helping of the hoggiest process I know of (Redhat/Fedora up2date) to 
be sure, and my fan stays hushed!

Anyone from IBM on the list taking note??? :-)
