mythtvsetup problem with recent Fedora kernels

I've just posted on mythtv-users; this is a heads-up.

When I was running 0.24* mythtvsetup couldn't see my dvb-t tuners after 
the kernel moved beyond 3.3.7-1.

I've just installed 0.25.2 and hadn't remembered that.  I tried 
mythtvsetup, deleted all cards and now can't see them.  That's in F16, 
kernel 3.4.7-1.
