Re: psmouse doesn't seem to reinitialize after mem suspend (acpi) when using i8042 on ALi M1553 ISA bridge with 2.6.11.11 or 2.6.12-rc5?

Hi Dimitry + linux-kernel,

I found a setting in the bios called "manual setting" for the pointing
device, under "advanced -> keyboard/mouse settings".  When set to
"manual setting," the button with a mouse picture on it (aka F3, when
pushed while Fn is held) will ... "jumpstart" the mouse, and it gets
picked up by psmouse again.  I don't know why it didn't work when I
had it set to "always enabled," or why it didn't used to work (I tried
"manual setting" when I was still using recompiled debian 2.6.8), but
it does now, with 2.6.11.11 even.

Perhaps the s3 suspend state confuses the always on setting of the
mouse and it doesn't "come back" or something.  Either way, this
setting seems to have fixed the one last nagging "feature" of the
p1120 running linux.  Minus the well-known CMS bug, which is
work-aroundable.  Now this p1120 is just dreamy with linux.

thanks for all the help.  Would an i8042.debug with the Fn+F3 pushing
help at all?  Perhaps it might tell us what's going on, and whether
this really is a "feature" of the p1120/ali m1533?
