:My apologies if this has already been discussed but ...

:There is a patch in the nvidia driver distribution that looks like so -
:
:Index: machdep.c
:===================================================================
:RCS file: /home/ncvs/src/sys/i386/i386/machdep.c,v
:...

    Well, I don't know if that is the right patch, but the issue with
    NVidia is that they are using %gs in the kernel and we aren't 
    saving/restoring it.

    I guess we should just start doing that and to hell with the extra
    few nanoseconds of switching overhead.
