Having just gone through this with an air2pc card, I can say that it is 
infact the issue.  The other small caveat I ran into, using a 2.6.16-1 
kernel provided by backports.org on a sarge system, is that some stuff 
has changed in input.h.  They have changed some types in there from 
'unsigned long' to kernel_ulong_t, and somewhere along the line, 
BITS_PER_LONG also got moved.  Or, at least, my compiles using the 
linux-headers-2.6.16-1-k7 get these 2 errors.  I had to modify my 
linux-headers to get it to compile.  Once I did that, I get good 
compiles, and I can now see my air2pc card.

Getting the output to work with my Hauppauge MVPMC box, now that's 
another story.......................
