All becomes less now that I FINALLY have some bug reports... (Thank you

Good to know.... cx25840 isn't backwards compatable with 2.6.3.... (cc
to Hans Verkuil, who maintains cx25840 added)
Hans, can you look into this?
FYI: I'm not completely sure that we are interested in backwards
compatability with 2.6.0 <= kernels < 2.6.8 ... I'll talk to Mauro about
that. If it's easy to do, then I'm all for it...... Don't be afraid to
propose patches.
Luca, you can edit v4l/Make.config and disable the cx25840 module from
the build by changing "M" to "N" , to disable it from building, and move
on to the (next error, hopefully none)

As I mentioned in my previous email, the dvb modules are disabled from
building in kernels prior to 2.6.12 ... You can force them to build by
editing Make.config, and changing the following:
remove these lines:
ifneq ($(KERNELRELEASE),)
CONFIG_VIDEO_BUF_DVB := $(shell test $(SUBLEVEL) -ge 12 -a $(PATCHLEVEL) -ge 6 && echo m)
endif
and instead, insert this line:
CONFIG_VIDEO_BUF_DVB := m
Please let me know how this works out for you..... I'd like to see all
the errors and warnings produced by this build -- this will help me to
fix backwards compatability with your kernel.
Thank you for the feedback!
-Michael
