Greek keyboard problems

After updating my tree, (the last time was four days ago) I can't login
anymore to kdm or xdm, because my keyboard writes greek letters and I
can't change this behaviour with Alt+Shift. Also Ctrl+Alt+F1 and
Alt+Ctrl+Backspace doesn't work anymore. I have to pass
Option "XkbDisable" "1" in my XF86Config to login successfully.
This is what I have in my XF86Config:

Section "InputDevice"
  Driver        "Keyboard"
  Identifier    "Keyboard[0]"
#  Option        "XkbDisable"    "1"
  Option        "XkbKeyCodes"   "xfree86"
  Option        "Protocol"      "Standard"
  Option        "XkbLayout"     "us,el"
  Option        "XkbModel"      "logiink"
  Option        "XkbRules"      "xfree86"
  Option        "XkbOptions"    "grp:alt_shift_toggle"
EndSection
