Thinkpad R51e is overheating very much even when idle except when run on 128 MHz (please see also bug #12826). AFAIR it is not preset on Windows and some earielr version of Linux (both I'll check out today).
The only way of preventing this to happen is to set by
thinkpad_acpifan controll to full-speed (i.e. removing the safety settings).
Could someone please recategorize this report appropriately?
(oh, and fixing it would be nice too :))

You do that, I lose track of things. So I am going to reply in the bugzilla interface. Sorry about that.
Maybe someday we could have a proper bug tracker setup that lets one deal with the bug reports over email... adding magic hidden approval headers to keep random spam at bay is trivial.
Executive summary: AFAIK, that thinkpad might be having hardware problems. IBM Thinkpads are supposed to operate at full number-crunching mode at full speed at any decent ambient temperature (in my experience, the T4x will deal with full load at <35°C ambient temps for long periods of time just fine, but they will be quite hot inside (CPU around 75°C, likewise the GPU, rest of the system approaching 60°C).
Thermal sink problems are common on IBM thinkpads, and are easy to fix if you can deal with taking it apart, cleaning things up, and applying a new thermal compound.

BUT, if we are doing worse in recent kernels and the submitter verifies this testing an older kernel, it is a bug and we need to find and fix it.

Agreed.
If we find that older Linux or some version of Windows works better than the latest Linux, then we have something we need to fix.
If they all fail, then this laptop's hardware issues do not justify the existence of the p4-clockmod driver in the kernel...
