I wonder why I get slightly different results for my 2.1 card. (I don't
really know this stuff.) The notable differences are "Unknown device 0002"
and "latency 64". Using kernel 2.4.17 and RH7.2.

I'm still trying to determine whether the driver is working for me or not. I
modified the tunertype entry for SPXXXX as you advised and gave the type=xx
parameter when loading tuner.o. I think it manages to load itself because
the log says this:

(I added the "tuner: chip is a '%s'" line myself to identify the driver.)

However, I haven't been able to get a successful tune yet. I'm using the
latest drivers from CVS. I'm doing this remotely over ssh from home so I've
got to try the X based software tomorrow at the office.

PS. I wonder if there's a simple, working test program that only takes
MHz/ksym/QAM as parameters and attempts to tune in? I mean something that
doesn't require those horrible .dvbrc files or anything. I have written my
own test program but I don't know if it works or not.
