I am going to start at some semblance of the beginning, and try to get
it all together, in one place.

I have just made sure that there is no module superio, smapi, or
thinkpad in the kernel.  

tp600x:~# lsmod | grep -i thinkpad | wc -l
      0

modprobe superio gives me, in /var/log/syslog...

Oct 15 22:27:06 tp600x kernel: thinkpad: I have registered to handle major: 10 minor: 170.
Oct 15 22:27:06 tp600x kernel: superio: Super I/O chip (non-virgin) in plug-n-play mode found at port base 0x2e. :-)
Oct 15 22:27:06 tp600x kernel: superio: I/O ports for Super I/O chip not available, but ignoring this.

and modprobe smapi, in /var/log/syslog

Oct 15 22:28:22 tp600x kernel: smapi: 32-bit protected mode SMAPI BIOS found. :-)



Now, as for the output of lsmod, do you want all of it, or just the
thinkpad stuff?

I will start with just the thinkpad, if you want more, just say so.

tp600x:~# lsmod | grep thinkpad ; lsmod | wc -l
thinkpad                2548   0  [smapi superio]
     41

tp600x:/proc/driver/thinkpad# for file in * ; do { echo $file;  cat $file; }; done
smapi
smapi module ver. 3.1 interfacing to 32-bit protected mode System-Management-API BIOS ver. 1.7 at address 0xc00fe9c4 through interface version 0.93
superio
superio version 3.0 controlling Super I/O chip at ioports 0x2e, 0x2f
thinkpad
thinkpad version 3.0 enabled to access modules: smapi superio rtcmosram thinkpadpm.

Well, duh!  I need to load up the rtcmosram module....

in /var/log/syslog, after modprobe rtcmosram...

Oct 15 22:32:21 tp600x kernel: rtcmosram: I/O ports for RT CMOS RAM not available, but ignoring this.

um, nothing at all.

no output, a lot of disk churning, and nothing.

Debian, used to be on unstable, moved back to testing a month or so
ago.  

tp600x:/etc# uname -a

thx for the help,
