gdb with pthreads on MPC8540

Has anybody got gdb 6.x working with the e500 (MPC85xx) to do
multithreaded debugging?
gdb gets a SIGTRAP upon a pthread_create, but doesn't seem to know what
to do with it. Seems like a simple configuration issue...

Configuration tested: Linux 2.4.26 on MPC8540 ADS derivative,
powerpc-8540-linux-gnu-gcc-3.4.3, libc-2.3.2 (libc.so.6), gdb (native)
6.2

Thanks
