[ltp] Freezes SuSE 7.1/7.2 and TP T 21

[linux-thinkpad@www.bm-soft.com]

My A22m has the ATI Rage mobility -m AGP 8 meg card, so in theory the
"savage" bug doesn't affect it.
But I still get moments when my mouse will be able to move around but not
click on anything (tab'ing, alt-tab'ing and alt-F4'ing don't work either).
On top of that the Icons on the desktop will highlight when the mouse
moves over them, but the buttons on the task bar don't react in the same
way.
The only fix that I've found is crt-alt-backspace, and restart the
Xserver.
I'm not fluent enough with Linux to know where I should be looking for
error logs or other such, so If you have any ideas I would be grateful.
The system is SuSE 7.2 with all the latest updates. (through the
auto-update feature)
It has also done it in the middle of a bzflag game as well, mouse movement
but no click ability...

IMHO, the problem is that apparently neither S3 nor IBM is wiling to
supply Tim Roberts, who developped the Savage driver for Linux, with the
complete specs for that chip. If you browse the archives of this list,
you will find several postings regarding the problems with simultaneous
display on LCD and external monitor with Savage based machines. Probably
this could be fixed - as well as the scrolling hang - if the specs were
available.
