copybench is listed as 'new BSD license'. Might need the pinging of its author whether he considers it GPLv2 compatible.

Frederic suggested dbench - although that's quite large as it includes a complete trace of a benchmark run.
We might want to do similar measurements to lmbench.
One nice thing would be to have a 'system call benchmark' set - one that measures _all_ system calls, and could thus be used to find regressions on a 'broad' basis. Syscall usage could be gleaned from the LTP project.
