Thanks for this response.

Let's try to figure out what might have happened. I didn't find any of
these problems with a valid configured kernel/X386, and some other people
already succeeded in getting a working version.

0. What does the kernel say during bootup? Does it say
   "co0<your video card type>" or "pc0 at .."
   If it tells you the latter, you should RTFM. The codriver package
   allows to build a compatibility kernel (which is basically the old
   pccons with old X11 fixes) and the new codrv. In the latter case you
   should use the configuration line from the sample config file which reads

device		co0	at isa? port "IO_KBD" tty irq 1 vector cointr

   instead of the standard line with pc0. Together with the new XServer
   the old line will cause many problems.
   If this does not help:
1. Which type of keyboard do you run? If this is a "converted XT-keyboard",
   it is likely, that it does not understand AT scan codes.
   However, you should have found the same effect in text mode already.
2. There is a known problem with ISO-Translation, which is done both in 
   the server and in the kernel. The server code is obsolete. This, however,
   only affects national keys with codes >=128.
3. Does the /dev/pccons exist, i.e. the device (usually major=12 minor=0) 
   to which /dev/console usually is mapped (or is it called /dev/vga)?
   Delete it! Also, if you modified the kernel conf.c, you might adjust
   the /dev entries, which my kernel relys on back to the default (of
   the fixit disk).
4. Which mouse type do you use? Do you use a busmouse? Or a mouse which
   is driven through the keyboard controller?
   There is one change which might afflict the behavior of the mouse in 
   the prebuilt kernel: The prebuilt kernel has cgd's com driver built in, 
   which comes with devices /dev/tty0[01] and /dev/ttyd[01], the latter of 
   which has the right minor number. I didn't get negative responses about 
   the mouse yet, because the codriver doesn't influence the serial lines. 
   The enclosed patch for tty_pty.c is not involved in this behavior.
5. Finally, there might be an address or interrupt conflict, although 
   this will usually make cause problems already in text mode (What happens
   to keyboard codes when moving the mouse?)

If you still have problems, send me your exact hardware and software 
configuration.
