The PCI adapter driver (e.g. saa7146) will call the PCI subsystem
to enumerate all devices on the bus. I think there was a change
between 2.4 and 2.6, but there is nothing the DVB drivers can do
about it.

udev in 2.6 might be able to solve this problem because you can configure
that a card in a specific PCI slot will have device nodes in
the /dev/dvb/adapterN you wish.
