Got it, & can't argue with that label.  Some of the labels I've 
applied to them are even more 'colorfull'.. Unforch, they are the 
*only* game in this town. :-(

Aha!  As in just 'dd' any line containing the .id in vim?

Good.  But where did you get the 2.0?  My 1.6 is only 2 weeks old here 
as thats about as long as I've had the card, but I haven't checked 
the dl page on Jacks site since yesterday sometime...

Humm, I see its labeled as for FC3, but since the kernel I'm booted to 
right now is linux-2.6.11.2-RT-V0.7.39-02, I'm going to make the 
assumption that I can use it till I find otherwise.

That kernel is locally built, using these patches, from my script:
VERP1="../2.6.11.1"
VERP2="../2.6.11.2"
VERP3="../2.6.11.2-RT-V0.7.39-02"
VERP4="../bk-ieee1394.patch"
VERP5="../2.6.11-forcedeth-fix"
VERP6="../Kconfig-1-patch"
VERP7="../Kconfig-2-patch"

The last 3 remove the '&& EXPERIMENTAL' from the respective Kconfigs 
for nforce2 stuffs.  If its not 'stable' yet, then lets get them 
fixed, this keeping stuff in experimental forever when half the 
planet is using them without any reported gotchas for extended 
periods just plain sucks.  So does the lag in getting 
bk-ieee1394.patch into mainline.  Firewire has been broken for quite 
a few moons now, so I fail to see the reason for the lag when the 
patch itself is demonstratably working great.  My hats off to Dan 
Dennedy & company there.

The only thing that didn't apply clean was Ingo's last RT patch, I 
dropped the ball on the EXTRAVERSION it was looking for in the main 
Makefile.  But vim fixed that right up after the fact.

So basicly, I'm cutting a fresh trail here, trying to scratch my 
personal itches and its not working too bad.  Not bad for an old 
fart.  I'll go see if the pcHDTV-2.0 version for kernels >2.6.9 works 
now, and get back to the list.  Thanks for the heads up on that.

I'll second that, this having to do everything to build a new kernel 
twice before its actually built and working is a major PITA.  I'm 
also doing the same thing with the spca5xx stuffs for a webcam.

Silly Q?  How much trouble would it be for me to just copy over the 
revelant src code modules once the patch has been applied?  I could 
make that bit of copying a part of my buildit26 script, a snippet of 
which you see above.  This is my src code tree builder.

Humm, it is the highest temp reported, as is temp2 in gkrellm, so I 
had assumed it was somehow a dup of the diode in the cpu, or of the 
thermistor against the bottom of it inside the socket.  Wrong 
assumption?

But I just in the last half hour managed to get it working again!

Somehow, in my playing with the CONFIG_BROKEN, (if you have an nforce2 
equipt board, never, ever, uncheck that option, its friggin dangerous 
to your sanity!) the building of the i2c-isa got erased from 
the .config.  Modularizing everything I needed, making sure the 
correct modprobe lines were in my rc.local, and fetching and 
installing the user portions of lm_sensors-2.9.0 to replace the 2.8.7 
stuff, and its suddenly working.

So now, sensors is working, as is gkrellm, and kino is working audio 
and all, but tvtime suddenly has a 2 second delay in anything it does 
including its on-screen clock sitting on a blue screen.  No video, 
just audio.

I haven't looked at that yet.

Its working again, see above.

Many, many thanks to Jean D., and all on this.
