How can I replace JDBC driver class when using JDBC4 Driver on JBoss?

Issue

In JDBC 4 spec defined DriverManager which reads content of META-INF/services/java.sql.Driver inside of JDBC driver, and loads it as driver class. So whatever you write in <driver-class> of DS file, the value will be ignored. For some proposes, I'd like to use specified JDBC class. Such as like using p6spy, I prefer to use com.p6spy.engine.spy.P6SpyDriver as JDBC class, instead of the real one in JDBC driver.
Now to settle of the issue, I have to delete services/java.sql.Driver from driver. It works well, but I reckon it's some awkward. Is there anyway in EAP to specify JDBC class?
