It was not being loaded by a modprobe cx88-dvb here, see my lsmod
listing from earlier today.

Having done an rmmod of everything related, installling the cvs but no
reboot, an attempt to modprobe cx88 back into the system gets a module
not found message.  So maybe I have to reboot anyway, brb.

I took these out before I installed the cvs to 2.6.14.3.  So here goes
a reboot.

As I said above, nxt200x wasn't being loaded by the modprobe cx88-dvb
statement.  I'm now rebooted after having done a cvs install after
modifying the v4l/Makefile, and its now broken again.  So I'm not
convinced that the nxt200x code has anything to do with my problem, at
least not yet.  Now I have to see if I can recover by blowing away the
/lib/modules dir and doing another make modules_install in the 2.6.14.3
tree, plus a cold reboot.  Nah, to heck with it, just rerun my makeit
script again, only takes about 9 minutes for a clean rebuild.  But this
cold reboot will take about 20 minutes, I have umpty gigabytes of
partitions that will e2fsck, /dev/hdd3 (180GB for amandas virtual 
tapes) taking at least 15 minutes, much of it with the progress bar
stuck at about 13%.  And another 80 GB partition is set for this round
too.  It sticks for 5 minutes at about 30%, e2fsck, version 1.35, needs
help IMNSHO. But thats what we have I guess... 

Anyway, rebooted, and it works again after modprobe cx88-dvb from a
cli. I let it run about 3 minutes, and got this in the messages log:

Is this related to the memory problems you commented on a couple of
times?  The system seems stable though.  And I've watched tv by the
hour many times, not knowing I should be tailing the log.

The log size so far for this week is ~500k.
