I'm confused by "Now it takes forever to get into X". What do you
mean by this? What did you use compiler switches did you use for the
DefaultGcc2AxpOpt variable in the server's host.def file?

In addition to Falk's suggestion, a couple of other things to try
with mplayer are turning double buffering and/or direct rendering
on or off. Sometimes they help, sometimes they do not.
To turn on double buffering in the X server, your XF86Config file needs
to have a 'Load "dbe"' line in the Module section. After restarting
the server, try starting mplayer with the -double switch. Direct
rendering (which may or may not work) is turned on in mplayer with
the -dr switch.
One other thought, if your running with a color depth of 32, try
reducing it to 24 or 16 bpp. Then there's less color data that
needs to be processed.
