mv /etc/rc2.d/S85power /etc/rc2.d/DISABLED.S85power is usually my
solution.

Other things that can almost certainly be blasted for a minimal
standalone system:

autofs (automounter)
init.dmi and init.snmpdx (if you don't want builtin SNMP)
lp (if you don't print from this box)
volmgt
sendmail (if you don't run it, obviously)
nfs.client, nfs.server and possibly rpc if you do no NFS

Disable dtlogin from even starting up by doing /usr/dt/bin/dtconfig -d.

If you will do all access remotely through ssh/scp, you may want to
consider nuking inetd completely.

Not all of these will speed things up much once the system is running, but
they will speed up booting by quite a bit.  They will also almost
certainly enhance security.
