No sorry, you're still not there yet.  Looks like you're still having 
some build problems here...

These errors still suggest that the system is still trying to link up 
modules that have been compiled in different ways or with different 
kernel versions :-(

Well I know that "omapX" corresponds to a TI architecture that happens 
to use an ARM core.  So this sounds like a compilation environment 
mismatch.  Last time I saw something like this the pvrusb2 module would 
fail to load.  Are you *sure* the driver actually loaded?...

If the pvrusb2 driver had loaded then you should have seen a number of 
additional messages in the system log generated by the driver itself as 
it goes through the steps to initialize the hardware.  I'm guessing you 
don't have those messages (otherwise I assume you would have pasted them 
here).  So possibly the driver didn't load.  Without the driver then of 
course /dev/video0 can't appear.  If you do "lsmod" do you see "pvrusb2" 
anywhere in the output of the command?
