We have discovered that there are multiple versions of
"the" driver. This means it is not easy to distribute
hacked copies or even to distribute a patch.
1) Here is Csaba's manual procedure (for the 64-bit library):

2) Here is another way of achieving a similar result. This is more
crude, but works better in batch files, i.e. doesn't require any
skilled feedback. This works for 32- and 64-bit libraries.
sed s/_ZNSt6vectorIiSaIiEE7reserveE/_ZNSt6vectorIiSaIiEE7reserveX/ \
orig/fglrx_dri.so > fglrx_dri.so
You can see that this is a way of making a variable quasi-local
(in the sense of being inaccessible to other modules) by maiming
its name.
