That's OK. You don't get any more messages after this:

> tda1004x: waiting for firmware upload...

It doesn't mean it failed. (I think you do get a follow-up message if it
fails.)

So at that point you should be ready to go. But there's a bug in 2.6.10
which means it tries to retune too often (or something like that), which
actually prevents the tda1004x from tuning except after a few seconds.
Already fixed in CVS, but for 2.6.10:
