Dave,
This won't help you this evening, but get yourself a copy of "How To Master
The Radial Saw" from http://mrsawdust.com/ to find out how to easily cut
this joint on the RAS. You can make a auxiliary fence that is 90 degrees
from the fence and cut this joint at 45 degs and not using the bevel.

The blade angle is 22 1/2 degrees but the best way to cut crown molding is
upside down and backwards with a simple jig. Check out the video clip at

Rocker (http://www.rocker.com) has a plastic jig for making these cuts,
as does Crown Jig (http://www.crownjig.com).
I have not used either one, but saw them at the Woodworking Show over
the weekend. The Rocker jig has you change which direction the 45 degree
is made (left or right). The Crown Jig just uses the left 45 deg setting
and you swap the jig around to make the cuts.

Well, Crown Jig is there, as is Rocker...but I suggest you make sure you're
over 18 before heading to Rocker. Could that have been Rockler?

That was pretty bad. Don't know how that happened. Yes, I meant Rockler.

Forget about a compound cut--it's too complicated even if you know
trig. Carpet tape four small blocks to your miter saw fence and cut
your moulding upside down. I like to set the saw at a (very) slightly
sharper angle to create a tight joint. Then I burnish the corner with
a screw driver shaft. I don't know how many times friends have asked
me to crown their house--it's not as hard as some say especially if
you can stand on your head.
Very few walls intersect at a 90 deg angle. Get yourself a angle finder,
someting that reads to 1 deg or less. That and some geometry will get you
the correct miter and bevel for the cut.
I bought a Bosch angle finder that calculates the miter and bevel cut from
the wall angle. eg if your corner is 88.5deg and you are using 30deg crown
molding the miter angle is 27deg and the bevel angle is 38deg.
Also, check out http://tinyurl.com/uhqm. You can download a spreadsheet that
gives you all the angles for the cuts once you know what the corner angle
is.
