Well, I haven't used the gdb interface with the 745x but I do know that
that with the telnet interface, you have to specify whether you're
setting a breakpoint on a virtual or physical addr (virtual is default,
IIRC). How you would do this with the gdb interface, I know not but
take a close look at the manual for the 745x--it *is* different from the
7410, etc--and you may find the answer.
