I don't know about the 2.6.8 source right now.
The Convergence CVS drivers still seem to do the
dvb_un/register_frontend stuff in the attach/detach_client functions.
This of course can lead to problems if the adapter is already
unregistered but not the I2C adapter. 
Actually, this should not lead to problms with the KNC cards. So, the
problem you mentioned must be caused elsewhere.

All KNC cards (and resellers like Typhoon, Terratec) should go in the 
budget-av driver because they have versions with analog video decoder
and the other budget drivers do not handle the GPIO ports correctly for
those cards (OK, right now neither does the budget-av driver).
Judging from the pictures of your card it also has the soldering
points for the SAA7113.
The budget-av driver only can handle KNC cards anyway. It is unlikely
that other budget cards with analog video will have the same decoder
and the same wiring.
