I have applied that fix from the bz entry to my grub.conf but have not 
rebooted as yet.  However if this asus_atk0110.ko module is supposed to do 
the same job, then obviously I do not have some other, required option set in 
my .config's for rc6 and rc7.  Directly choosing it doesn't seem to be 
available in a make xconfig.  What am I missing?

Thanks, Stefan.
