I have an old box which I'm pretty sure has a cpu about 1.6, non-dual core.
Tomorrow,  (too much noise at this hour of night here!)  I will try 
either/or Kworld 210, Pinnacle 310i, Kworld 220.
I will  try  both current v4l-dvb and that patch of yours in  
tda10046x.c, and see what happens.

Is it worth trying different msleep values?

All I can think of is this is a relatively recent event with this 
"revision FF" business,
but I can't be exact as to how long ago I noticed it.

OK, tried all that.

For Hermann, cards are:
Pinnacle 310i
Kworld VS-DVBT210RF
Kworld VS-DVBT220RF

It's not very predictable.

Either with a fresh install of ubuntu 8.04 (no hg v4l-dvb yet)
(Linux ubuntu 2.6.24-18-generic #1 SMP Wed May 28 19:28:38 UTC 2008 
x86_64 GNU/Linux)
or install v4l-dvb,
with your patch or not,
it varies whether reboot, shutdown, power cycle.
Sometimes the firmware loads no problems, sometimes not at all.
The firmware file is the one which comes with ubuntu 8.04,
so I don't know why/how it changes revisions.
The same things happen if I use the revision 29 from lifeview.

The card which presents no problems is the Kworld 220, which of course 
is not a hybrid,
and this card has 2 x i2c eeproms: 24c02n, 24c256n

The others have just a 24c02n.

So, perhaps this indicates an timing error somewhere between checking 
for an on-board eeprom, finding none,
and then locating/loading a firmware file.

I notice someone is having similar problems with an Asus card.
