I should admit I don't have a single clue about TV tuners :-)

I'm not _entirely_ sure what you're saying but if I understand correctly,
you're saying you believe the kernel driver doesn't work, because tvtime
_did_ work with a different card.  That doesn't necessarily mean that you
need to jump into compiling kernel drivers, it could just mean the correct
driver isn't getting loaded correctly.

Before or after you compiled your own driver?  What driver did you compile?

Well, a quick google for cx88.ko gives me this link: 

"HDTV capture driver for cx2388x
Sep 30, 2007 ... Here's a not-so-brief overview of the contents in case
you're interested: common / Sources for cx88.ko, wich implements channel
configuration ... -

So, BSD at least things that the cx88 driver is correct for cx2388x devices.

In any case, if the driver you compiled was called something else, and this
dmesg output is after your install, we can see that your driver wasn't
