This patch breaks synaptics support, because the pktcnt variable is
now used by the synaptics code. (Previously the synpatics code used a
private buffer, which was unnecessary and therefore removed.)
Reverting this patch makes the touchpad work again for me using kernel
2.6.0-test5-bk8:

Sorry for introducing the breakage. Applied to my tree.

I'm not sure how resume using old PM code is usefull...
Well at least its usefull as documentation :-).

    Vojtech, how do you feel about the psmouse_imps2 patch[1] that's
been in -mm since -test4-mm5?  Several people have told me it's been
useful for them, to either make their Belkin KVM switches work with
Logitech mice or to disable the Synaptics touchpad driver at runtime
and still be able to use scroll mice.

[1] http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test4/2.6.0-test4-mm5/broken-out/psmouse_ipms2-option.patch

    I could write a patch to selectively enable or disable all the
different mouse drivers if you would prefer something more general.
