I'd like to give the other maintainers a voice in this, as they might not have 
noticed this patch. Hence the CC to linux-dvb; if nobody has abjections 
against the method used in the patch I'll commit.

I noticed your post about 'cross compiling' the dvb drivers on the linux-dvb 
mailing list, but I'm a bit stumped that you had to do so much considering 
the great benefits of the kbuild system of 2.6. As an example I'll write up a 
quick summary of what I do:

1. Make sure that you have a kernel source with the correct configuration of 
your current kernel somewhere.
2. Replace the line in build-2.6/Makefile that says
KERNELSRCDIR := /lib/modules/$(KERNELRELEASE)/build
to
KERNELSRCDIR := /where/ever/your/current/kernel/on/this/or/another/box/is
3. Compile as many versions of your driver(s) (usually this, or similar 
approaches, works with other drivers too)

I use this to compile both kernel and drivers for a epia m10k on a dual athlon 
mp :)

Dunno about this though... :|
