X doesn't start

[Andras Simon]

This is the last thing it says:

  The XKEYBOARD keymap compiler (xkbcomp) reports:
  > Internal error:   Could not resolve keysym XF86TouchpadOn
  > Internal error:   Could not resolve keysym XF86TouchpadOff
  Errors from xkbcomp are not fatal to the X server

There are no errors in Xorg.0.log. This is on an updated F14, where X
used to work.

Before this happened, I removed a few packages (on an Eee PC with 4G
SSD one has to hunt for dispensable packages) listed below, but I've
since reinstalled them and still no joy.

pyOpenSSL
python-paste
smolt
smolt-firstboot
metacity
firstboot
system-config-keyboard
plymouth-scripts

There were probably updates after the last succesful start of X, so,
for all I know,  the problem may be one of them.

I'd be grateful for any ideas on how to poceed.
