I can confirm the problem on Ubuntu 10.10 on a Lenovo W500 with kernel 2.6.35-30-generic-pae-tuxonice (and every other recent kernel I've tried).

Can't boot with BIOS AC setting on Balanced, which would allow frequency scaling to kick in at lower temp to keep things cool.

Temp climbs up to >90C under full CPU load, because fan never goes to "disengaged" mode (~4900 RPM) when set to "auto." If I manually set to disengaged, then temp maxes out at 70C or so.
