I'm using patched Debian kernel and lenny Xorg and seriously had  
problem A when I first applied the patch. Based on /usr/doc/xserver- 
xorg-input-synaptics/README.alps, I added the appended section to my  
xorg.conf.

I didn't see problem B. Have you looked at the output from "synclient - 
m 10"? The "f" column indicates the number of fingers detected and "z"  
is pressure on the trackpad. Pressure is always either 0 or 128 for  
me; if it has actual pressure values on newer kernel/X, you might need  
to tune FingerLow/High.
