Thanks a ton! I am really excited to see that you guys made so much
progress over the past few days! Of course, I immediately had to give it
a try :)

And here is a first support request - the kernel module does not load
for me :(

I have a Thinkpad T42, running SUSE Linux 9.3 (Kernel 2.6.11 with SUSE
patches). The APS works on Windows, so I know the accelerometer is there.

I have downloaded the sources from your site mentioned below, ran "make"
and "make install". Then I created the /dev/hdaps0 device node by
running "mknod hdaps0 c 228 0". (I picked this out of another message in
the discussion)

However, running "modprobe ibm_hdaps" only yields an error:

FATAL: Error inserting ibm_hdaps
(/lib/modules/2.6.11.4-21.7-default/kernel/drivers/misc/ibm_hdaps.ko):
No such device or address

In /var/log/messages, I only see:

Jul  4 07:17:20 metis kernel: ibm_hdaps: unsupported module, tainting
kernel.
Jul  4 07:17:20 metis kernel: init 1 50239260

(The last number differs every time I load the module)
Passing "debug=1" did not really reveal any more info. How could I
provide you with more detail?

I also tried to load Henrik's module, but it also spits out an error
"failed to allocate I/O", then a long number of "latch_check" lines and
"initialize() ret: -5".

Maybe the accelerometer on the T42 uses a different port range? Or could
it be that some other kernel module is blocking this I/O range? I have
no clue...

Maybe there is some kind of all-purpose ATA command that instructs the
disk drive to park the heads? Jens, could you give us a hint on how a
userspace application would do that?

Should we try to move the sources over to the hdaps.sf.net CVS tree?
Even though I am more a Subversion fan, having at least some kind of
version control would make it easier for others to participate and make
sure we can send patches against the latest version.

Attached please find a diff against ibm_hdaps.c I found on the URL above
- - I moved some stuff to a separate header file (attached) and added
printing out the driver name and copyright during module initialization
(taken from Henrik's files). I also added an "uninstall" target to the
Makefile.

I hope you find it useful!

Bye,
	LenZ
