A lot of us copy it down by hand, at least the function names.
You might use the recently added /l option to trace in ddb,
which puts the backtrace in the message buffer. Then after a warm
reboot on systems with a persistent message buffer (i think this
is true for sparc64), you can use dmesg to get a copy of the trace
out of memory.
