    Hi,

Wine applications such as Firefox seem to be running very slowly on my
-current box. I am seeing the following message constantly:

xlib: extension "MIT-SHM" missing on display ":0.0".

My /etc/X11/xorg.conf has:

    Section "Extensions"
	    ...
	    Option "MIT-SHM"   "Enable"
    EndSection

Xorg.0.log says

    (**) Extension "MIT-SHM" is enabled
    (II) Initializing built-in extension MIT-SHM
    MIT-SHM extension disabled due to lack of kernel support

My kernel config has

    options SYSVSHM,SYSVMSG,SYSVSEM

kldstat says the modules are present:

    lizzy:~% kldstat -v|grep sysv
		    137 sysvmsg
		    142 sysvsem
		    146 sysvshm
    lizzy:~% 

How do I turn on kernel support for the MIT-SHM extension?
