I can't find any screen anywhere in myth-setup that will allow me to
perform a "channel scan".

I think so:

mythtv$ ./configure --enable-dvb --enable-proc-opt
...
DVB support      yes [/usr/src/linux-2.6.11-gentoo-r6/include]
...

config.h:
	#define FFMPEG_CONFIGURATION " --enable-dvb --enable-proc-opt "

config.mak:
	CCONFIG= linux backend release using_oss using_alsa using_arts using_ivtv using_joystick_menu using_dvb using_x11 using_xv using_xrandr
config

mythtv-setup lets me choose the DVB card type and seems to properly
identify the Air2PC cards as "Nextwave nxt2002 VSB/QAM frontend
ATSC".  I just can't get the cards to tune with MythTV.  'azap' from the
dvb-apps/dvb-kernel tar-ball indicates a solid signal lock:

 mythtv $ azap -a 0 KHOU
 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
 tuning to 575000000 Hz
 video pid 0x0000, audio pid 0x0000
