Indeed it is. I am working with a fairly minimal system on a Xilinx 
Microblaze soft-core CPU. I have udev installed, but I'm not sure about

Simply because I wasn't aware of the misc_dev API :) But that does look 
like a nice abstraction that will save me some boilerplate, so thanks 
for pointing that out.

Thanks,
