Not quite. PERMEDIA3 is the driver name, while RX would be the chip.
The big problem is that you always have some higherlevel code (like
Mesa) and some lowlevel driver backend. They both need to be mentioned
somewhere in the render-string (incl. version).

I'm pretty much relicutant to adopt any scheme as a standard. Why ? The
render-string, along with the information in a config-file is for us
key to customer support. The better we can figure out what a customer
is running that better. If there needs to be a different string to
make it easier for customer support, then we'd like to change the
string.
