Well, I seem to have hosed a registry entry.

HKEY_LOCAL_MACHINE\system\currentcontrolset\control\virtualdevicedrivers

(http://support.microsoft.com/kb/314452/en-us).

I've updated the registery as indicated, and the error has gone away, but
things still aren't right.

As a result, my "16-bit subsystem" (i.e. COMMAND prompt, which I use
a lot for various development tools for work) is quite hosed.  Screen I/O
seems to be about 110 baud, and many things do not work (if the program
tries to do graphics, for example).

To make things more irritating, thing work properly *ONCE* when the
system is first booted up.  After that, it's back to broken.

This is an IBM Thinkpad, T42p, with an ATI Mobility Fire GL T2.

I've nuked the ATI drivers and re-installed fresh, no luck.

So,
   1) Does anyone have any clues?  Or do I have to nuke the OS and
       try again?

   2) Could people tell me what the values are for the above registry key
       on their system?  It might help me track things down.

Thanks,
   Bill
