Ok, testing the pvrxxx_port-09042007.tgz port, still with a pvr-350,
and still with this version of -stable:
tingo at kg-quiet$ uname -a
FreeBSD kg-quiet.kg4.no 6.2-STABLE FreeBSD 6.2-STABLE #17: Sat Apr  7
18:45:15 CEST 2007     root at kg-quiet.kg4.no:/usr/obj/usr/src/sys/QUIET
amd64

I load cxm_iic and cxm, and get this in /var/log/messages:

I can do 'pvr250-setchannel 196.25', and get this in /var/log/messages:
Apr  9 12:31:47 kg-quiet kernel: before tuner_command!
Apr  9 12:31:47 kg-quiet kernel: tuner: tv freq set to 196.25
Apr  9 12:31:47 kg-quiet kernel: tuner: tv 0x0e 0xb3 0x8e 0x02

Then I run 'gmplayer -cache 8000 /dev/cxm0' and get static (translated: it works, but there isn't any signal).
As soon as I try 'pvr250-setchannel -m 4' my machine panics (buit this is perhaps expected).
