Here's what the full "dmesg" output looks like for a working PVR-250.
Note that different cards may have different tuners, but the overall
group of messages should look pretty similar to this:

 ivtv0: Initializing card 0
 ivtv0: Autodetected Hauppauge card (cx23416 based)
 ivtv 0000:05:03.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
 tveeprom 1-0050: Hauppauge model 32062, rev B185, serial# 2842715
 tveeprom 1-0050: tuner model is TCL 2002N 6A (idx 85, type 50)
 tveeprom 1-0050: TV standards NTSC(M) (eeprom 0x08)
 tveeprom 1-0050: audio processor is MSP3445 (idx 12)
 tveeprom 1-0050: decoder processor is SAA7115 (idx 19)
 tveeprom 1-0050: has no radio, has IR receiver, has no IR transmitter
 ivtv0: Autodetected Hauppauge WinTV PVR-250

 ivtv0: Registered device video25 for encoder PCM (320 kB)

Those "registered" messages just above are what's most important to see.
Lacking those means your kernel is missing some driver(s).
