Howdy Luke,
	I have the Nebula DigiTV PCI card working on a 2.4.23 kernel, based on
the CVS tree (checkout on 2003-11-29):
(ref, http://www.linuxtv.org/developer/dvb.xml which suggests:

Nebula DVB-T PCI card

This driver was written by Florian Schirmer and is part of the
dvb-kernel CVS tree.)

Ref.  http://linuxtv.org/cgi-bin/cvsweb.cgi/

I checked out the 'dvb-kernel' module as shown, entered the 'build-2.4'
directory and followed the instructions in the README to build then used
'insmod-bt8xx.sh' to load the modules (shown in lsmod) 

from lsmod:

unix$ ./tzap "TEN Digital"

Note that the signal level and snr shouldn't be 0, but xine works
showing all channels!

I hope this helps,

Paul.
