The following little fix will give Your's X11 session a voice back, and of
course the above mentioned PCMCIA cardmgr too:-). Some grepping in the
XFree server sources and, after localization of the ioctrl in effect, in

patches.

BTW. Why did somebody feel the innocent need to remove it in some of the
recent kernels? Na na na....
