More than 4 cards were only supported with the old "DVB" driver
with CONFIG_DVB_DEVFS_ONLY enabled in dvbdev.c. I can't remember
why this was dropped in dvb-kernel.

The minor numbers are the same as for adapter0 which is why it doesn't
work. The best solution would be to use the extended minor number
range in 2.6 kernels. For 2.4 one could use a second major number.
