The first thing that comes to mind is to set
RC_PARALLEL_STARTUP="yes"
in /etc/conf.d/rc

However, lots of things rely on the net.* scripts before they start.
Have a look at the output of
`egrep need.*net /etc/init.d/*`
and you'll see every service that will wait for your network script to
start (which means waiting for a dhcp response)

The second thing that came to my mind, and this would probably rely on
you only getting a dhcp for the wireless, and not the wired lan, would
be to "roll your own" /etc/init.d/net.eth1 script.  Make it exactly the
same as /etc/init.d/net.lo, but in the depend() function, add something
like "provide mywireless".  This, coupled with parallel startup, should
mean that no other init script will require your net.eth1 connection and
it can take time without holding other scripts up.

I've never tried this idea, so it could be fundamentally flawed, but its
just a thought!
