I have a Thinkpad W520 and can confirm that Linux (Kubuntu 10.10) will run just fine with the different BIOS option. I can even run Company of Heroes under wine and it runs pretty decently. Not sure what the extra penalty to battery life is under this different BIOS option, but the lappy still runs at least 5 hours. btw, I use the proprietary nvidia drivers (just run their install scripts and it should work fine).
