Sorry all, my error.  Turns out my kernel header files did not match the running kernel.
Mandriva do not provide header files for released kernels - you have to install the kernel source and build.  Until recently you could just run make on the default source and get compatible header files.... however as of Mandriva 2008.0 the mandriva installer installed kernel 2.6.22.18-desktop-1mdv, but the source I got was 2.6.22.18-1mdvcustom - so when editing the Makefile to remove the custom label I inserted desktop as well.  Big mistake!  

Solution, build a kernel (called 2.6.22.18-1testbuild1mdv) install it, reboot into new kernel, then build the v4l-dvb code, with make release VER=2.6.22.18-1testbuild1mdv and install.  Now a frontend is found when the af9005 is plugged in, and no kernel oops with dvbsnoop or when unplugging.  I now have it running in Kaffene.

Thank you to any that looked at the original report.
