I have a google apisSyncing gmail calendar AND google apps calendar to droid-x

[SoonerLater]

I have a Google Apps account AND a Gmail account. My Droid X gives me the option to sync the calendar of my gmail acct, but not the calendar of my Google Apps acct - even if I deselect to sync my gmail calendar first. I would prefer to sync both to a single calendar app (like I sync both email accts to a single email app on the droid now) but would accept using two calendar apps. How can I do this?
