PS2 mouse changes for 2.6

PS2 mouse changes for 2.6

[walt]

I get good results from last night's PS2 mouse patches.  My one
problem machine now works perfectly again without the psmouse_noext
parameter I've been using for several months.

Two observations:

I see no deprecation warnings when starting the kernel with
psmouse_noext, which I was expecting to see.

The mouse is announced as a 'generic wheel mouse', but it is
really a Kensington Orbit trackball.  Unfortunately I don't
have a wheel mouse to test with, so I can't comment there.

Thanks for the fixes!

It is emitted with KERN_WARNING severity and is not necessary seen on
the console. Check you dmesg.

The kernel does not really distinguish between different hardware
manufacturers. It tries to recognize Synaptics, Logitech and Genius, but
it relies on mouse responses to various PS/2 protocol probes. Anything
that responds to IntelliMouse (imps) protocol probes but does not respond
to ImtelliMouse Explorer (exps) probes gets labelled as "Generic Wheel
Mouse".

No warnings in dmesg on two different machines booted with psmouse_noext.

I am NOT complaining -- my mouse works better today than yesterday :0)

Is there anything I can do to help with this problem (?)

OK, when I switched the parameter processing to the new technique I missed
the fact that it requires specifying prefix (module name + '.') when the
module is compiled directly into the kernel. Therefore in the lastest -bk
you have to pass "psmouse.psmouse_noext=1" to the kernel for it to be.
recognized.

Since we already have an unique prefix (psmouse) for all parameters and
changing parameter names at this time is not desirable (IMHO) I propose
the patch below to restore the old behavior.
