ACPI problems with Dell laptops? (was: Jerky keyboard and mouse)

[Sune Wettersteen]

I'm on a Dell 500m and acpi seems to work fine, other than it doesn't
register lid opening, which means that when I close the lid and open it
again, the screen is still blank. Does anyone know about this problem?
I can partly relate to the mouse issue. My mouse is very sluggish and its
slow to register when I hold a button. From the time I (lets say) start
dragging on the desktop to the time it registers I'm holding down the
button, the mouse cursor has already moved quite much, which makes working
with graphics (inkscape) very annoying. Anyone had similar problem?

The alps touchpad works fine after being set up correctly in moused though.
Keyboard also works fine and gets registered.

Indeed.  After all, you're quoting yourself :-)  I said:

In particular, I didn't get any dropped characters.  And I note that
I've misquoted the model number; it's an Inspiron 6000, not 6100 (I
don't think the latter exists).

I would have been interested to hear the results of the ping.  But
yes, it would be nice to get the machine to work nicely with ACPI.
