Yeah, ok. You may want to change that message from the generic sounding 

Unable to set number of SCO buffers : please upgrade your Kernel!

to something like: 

Unable to set number of SCO buffers: Please apply kernel patches from
patches directory in the plugz source to your kernel and reboot with
that kernel. 

I'll try and find time to build a custom kernel and test it, but that
might take a while. I try and avoid building custom kernels these
days. ;(

If this patch is needed, is there any move to get it pushed to
upstream? One of the reasons I was very happy about this new setup was
that I didn't need to compile an out of tree module with every kernel
update, but now it's worse if I have to make a new kernel with this
patch. ;(
