This is what I see:

cxm0: <Conexant iTVC16 MPEG Coder> mem 0xf0000000-0xf3ffffff irq 17 at
device 14.0 on pci0 cxm_iic0: <Conexant iTVC15 / iTVC16 I2C controller>
on cxm0 iicbb0: <I2C bit-banging driver> on cxm_iic0
iicbus0: <Philips I2C bus> on iicbb0 master-only
cxm0: Philips FI1236 MK2 tuner
cxm0: SAA7115 rev 1 video decoder
cxm0: MSP4448G-A2 audio decoder
cxm0: [GIANT-LOCKED]
cxm0: [ITHREAD]
cxm0: encoder firmware version 0x2050032

I suppose that's OK? Please note I had to remove IR from sources because
my card doesn't have it.
Anyhow, I tried to configure it using mythtv-setup and whatever type of
card I tried it always displayed "Failed to open". I've updated the log
at 

http://saul.homeunix.org:8000/tmp/mythbackend.log

Does it mean I have to set up channels before backend can start? Or does
it mean the card cannot be used?

I appreciate your help.
