I forgot to mention that usually I have the rest of the acpi modules loaded as 
well (instead of just 'container' as my lsmod output showed), but that 
particular try, I tried stripping down to the absolute bare minimum.  Here 
are the acpi modules I *usually* have loaded:

video                  16260  0
thermal                13576  0
toshiba_acpi            6164  0
fan                     4740  0
processor              22708  1 thermal
button                  4224  0
container               4608  0
ac                      4996  0
battery                10244  0
