The driver is robust. Currently "cat /proc/apm" is returning -1 for HDQ based 
batteries, after the patch a sane number is reported (good for the product). 
Regarding "acme replacement batteries". They will charge, "cat /proc/apm" 
will return a wrong voltage number, but we don't know the battery curve of 
these batteries anyway. The best I can think of is to have a sysfs file 
somewhere to switch between ADC and HDQ...and move this prob' to userspace.
