I have a Dell Latitude XPi and was having problems that were fixed by the
patch below (ymmv, so be sure you can back out... if you want the
debugging patch mentioned that I'd tried first, I'll send that too but it
should be in the "hackers" archive on freefall). Be sure you have psm0
turned on...
good luck!

Now, may I assume you got the messages in the following order, the
return code was "fa" ("zz" in the fifth line) and the keyboard did NOT
freeze?
sc0: enabling tty intr. (set_keyboard)
sc0: about to send command and data (set_keyboard)
sc0: kbdc is LOCKED!! (scintr)
sc0: kbdc is LOCKED!! (scintr)
sc0: command:xx data:yy ret:zz (set_keybard)
~~
sc0: kbdc is LOCKED!! (scintr)

Please revert to the original syscons.c and apply the following patch.
It is known to work, that is, kbdcontrol can change key repeat rate
and the X server doesn't lock up the keyboard.
This patch doesn't generate debug messages, so it will be more
suitable for daily use than the previous one.
