I'm guessing Linux support is pretty much (or completeley) non-existent 
for that chip.  If anything, you may get a Gatos-style capture 
support--which is not V4L, so won't work with Myth.  See
http://mythtv.org/docs/mythtv-HOWTO-3.html#ss3.1 in the section "Video 
Capture Device" under "Frame Grabbers" where it says:
NOTE: The ATI All-in-Wonder cards (which are not the same as the ATI TV 
Wonder, TV Wonder VE or TV Wonder Pro) will not work as a MythTV capture 
device because the GATOS http://gatos.sourceforge.net drivers that are 
available provide only a limited subset of the V4L API. The TV Wonder 
series of cards are supported by the Bt8x8 Video4Linux driver.

(The All-in-Wonder cards also use the Theater chips.)
