Problem with italian keyboard

[Giannandrea Castaldi <g.castaldi@quinary.com>]

Hi,
I've just installed debian unstable on my laptop (acer travelmate 342T) 
and I've some problem with the configuration of the keyboard (italian). 
I've configured the keyboard using kbdconfig and setting 
qwerty-italian-standard.
Working with the console (without X11), I can use all the keys of my 
keyboard (included àèìòù) for writing login and password but after I'm 
logged I can use only english keys.
I thougth it were a problem of my locales that initially were all to 
POSIX but after I set LC_ALL, LANG and LC_TYPE in my .bashrc nothing is 
changed.
I've configured in my system following locales:

gcast@calcolino:~$ locale -a
C
en_US
en_US.iso88591
en_US.utf8
italian
it_IT
it_IT.iso88591
it_IT.utf8
it_IT.utf8@euro
POSIX

and added in my .bashrc the following lines:

export LC_ALL=en_US
export LANG=en_US
export LC_CTYPE=iso_8859_1

Perhaps LC_TYPE isn't correct because with locale I've the following output:
gcast@calcolino:~$ locale
LANG=en_US
LC_CTYPE="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_COLLATE="en_US"
LC_MONETARY="en_US"
LC_MESSAGES="en_US"
LC_PAPER="en_US"
LC_NAME="en_US"
LC_ADDRESS="en_US"
LC_TELEPHONE="en_US"
LC_MEASUREMENT="en_US"
LC_IDENTIFICATION="en_US"
LC_ALL=en_US

Any suggestion?

Thanks.
