this hits me only by accident, reading through backlash, but I added
that Asus Tiger Revision 1.0 with subsys 1043:4857, with a huge delay
only. (approximately 1 1/2 years)

The development and testing for the new tuner types was done only much
later on freely available stuff, a so called Asus Dual _non_ OEM

Not to tell what we did all see thereafter, but that all was at least,
with only one exception, valid using the PCI subsystem as unique

Luckily, as far as I can see, we have only a fictional radio device on
your "new" variant left over.

This can still be very annoying, but won't do any harm, except wasting a
users time, bad enough, but at least not any radiation from that sort of
radio flaw.

Since the PCI subsystem is identical with mine, still around somewhere,
with radio support, either take that dead radio device for now or a last
chance is to discover, if any eeprom differences are there to eventually
filter that minor, but unpleasant shortcoming for those trying in vain
on the radio.


To restore the power on a failing power plant in urgent need of it seems
to be a good idea, after six or seven days ...

All my excuses for the failing radio device on that not yet seen OEM
stuff, but I can ensure, to piss on it doesn't help any further.

Hopefully it does help in that other case.
