Actually there are QAM HDTV cards available.  I've been successfully
using the pchdtv HD-3000 with my QAM cable connection for a while now. 
You might want to go to http://www.pchdtv.com and browse through the
user/support forums there to learn more about them.  Keep in mind that
these cards only support unencrypted QAM, so you're likely to only get
local broadcast stations in HD over your cable.  You won't be able to
receive premium HD channels, etc.  You most likely wouldn't be able to
get these via a firewire connection to a cable box either though.
