That was my assumption... Hmm, here are the three drivers that I loaded
through /etc/modules back when I had only the 5500 card in my mythtv box:
cx88_alsa
cx8800
cx88-dvb
When I had just the one capture card I ended up using only the analog part
of the 5500 in "production-mode". FWIW, it seemed to work best using the
'v4l analog' config option in mythtv-setup rather than using the dvb
interface. I never did get mythtv to work reliably with both the analog
and the digital parts of the card in the same configuration. That was
maybe a month after the 5500 was first released though so the drivers were
pretty rocky. I ended up getting a PVR-150 handling the analog channels
and am using the 5500 to record digital only. It's working pretty well.
For this dual card setup I am manually loading the following drivers:
ivtv
cx88-alsa
cx88-dvb
At least one of the three is pulling in the cx8800 driver which (I think)
handles the analog part of the 5500 card. The cx88-alsa would probably get
pulled in automatically too but remains for historical reasons.

Hopefully you just have to load the cx8800 module.
Here is a (trimmed) lsmod dump showing all of the video related modules for
my PVR-150 + HD-5500 system (some of the modules are only used by the
PVR-150/ivtv card but some appear to be used by both):
