It seems that this bug is triggered by the following commit, which has
been tested to fix the issue on Maverick.  This fix is already in Natty,
and has been proposed for SRU to Maverick:

  commit f8313ef1f448006207f12c107123522c8bc00f15
  Author: Jiri Kosina <jkos...@suse.cz>
  Date:   Sat Jan 8 01:37:26 2011 -0800

    Input: i8042 - introduce 'notimeout' blacklist for Dell Vostro V13
    
    i8042 controller present in Dell Vostro V13 errorneously signals spurious
    timeouts.
    
    Introduce i8042.notimeout parameter for ignoring i8042-signalled timeouts
    and apply this quirk automatically for Dell Vostro V13, based on DMI match.
    
    In addition to that, this machine also needs to be added to nomux blacklist.
