1850:0000 is the same number that I always get - from both of my cards 
installed in the same machine. Interesting observation that you make 
about whether the machine was reset or went though a power down - this 
corellates with one of my theories. You've inspired me to test this, 
which I'll do once I get the whole confounded mess to boot again.

For interest's sake - you are using FC4 - on what hardware? It would be 
interesting to see if there are similarities. My experiences are on:
gentoo (previously SuSE OSS 10.0) 64 bit.
Gigabyte GA-K8NSC-939 motherboard with NFORCE3 chipset
2 x Compro VideoMate DVB-T300
some brand of video card based on NVidia 6600GT, 256MB
300GB SATA disk

I am currently using the 2.6.16 kernel as there has been a fix since 
2.6.15 relating to loading multiple saa7134 cards and getting sound 
working on all of them.
