Try out the uaddr() action:
# dtrace -c date -n 'pid$target::main:entry{ uaddr(0x8062578); }'
dtrace: description 'pid$target::main:entry' matched 1 probe

dtrace: pid 105537 has exited
CPU ID FUNCTION:NAME
0 59934 main:entry date`clock_val
Unfortunately, the only place this and some other actions and subroutines
are "documented" is in dt_open.c:
http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libdtrace/common/dt_open.c#134
Documenting these would be a great way to contribute to the DTrace community.
If anyone would like to take a whack at updating the docs, here's the section
where they should be added:
http://wikis.sun.com/display/DTrace/Actions+and+Subroutines
And here's some more general information on update the docs:
