Maybe I set the limits too low on th pbooks. It looks like there's a
protection in case of too long overheating, and i don't find out where it
could be set in the docs.

(btw, can you check that the patch you applied is the correct one, where
LIMIT_REG reads:
    static u8 LIMIT_REG[3]   = {0x6b, 0x6a, 0x6c}; /* local, cpu, gpu */
and not
    static u8 LIMIT_REG[3]   = {0x6a, 0x6b, 0x6c}; /* local, cpu, gpu */

If this is not the case, invert the two firsts and try again...)

if it is, you can try to set the limits higher by using
"limit_decrease=-10" parameter.

If you have MacOSX installed and if it is possible to read temperatures
values in this OS, you can also check at which temperature the fan starts.

Thanks,
