Description of problem:
after i digit a space key the backspace don't work correctly, the
cursor go back for a character and return a step next then wait
sometime and repeat spaces forever, for stop it i need to press a
key. The problem seems appare only after a space key pressed, in all
the start mode (init 3 / 5) and during install too.
The ps is an Athlon 64 3200+, mb asus k8v, 1Gb ram, logitech cordless
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. open a terminal
2. press space key
3. press backspace key
Actual Results: the cursor make a step back and forward and start to
repeat the spaces

after a deep check i have found a new clues for correct it. first the
problem is into the kernel and seems that when i press backspace key
it generate a press event and a release, but after arrive two unknown
signals and another space key pressed without release. in some cases
i have see other unknown signal when i press a letter or other keys...
but it appened in very few times.

since the X server is also reading /dev/console ]
press any key (program terminates 10s after last keypress)...
