AFAIK this verification is only done in --with-colons mode because in 
this mode the trust level is calculated and shown.

Actually --list-keys doesn't seem to be any faster in --fast-list-mode.
Here's a small test:
- --------
ingo@erwin:~ > time for a in `seq 1 10`; do gpg --list-keys >/dev/null; 
done
real    0m12.115s
user    0m11.430s
sys     0m0.190s

ingo@erwin:~ > time for a in `seq 1 10`; do gpg --list-keys 
- --fast-list-mode >/dev/null; done
real    0m12.076s
user    0m11.400s
sys     0m0.180s

sys     0m9.800s

- ---------
As you can see the --fast-list-mode option makes no difference for a 
simple --list-keys. Only if you also use the --with-colons option you 
can save a lot of time by using --fast-list-mode.
