IMHO, the _Hardware_ is not the problem at all, but the OS is. You need 
to use a decent realtime OS (or none) to get msec resolution. There are 
several projects to make Linux more realtime aware. Those that are 
usable for _real_ realtime stuff (i.e. the realtime-processes need to 
meed predefined latency specifications without any exception) use a 
realtime OS below Linux and have Linux run as the lowest priority 
process of same.
