What does this have to do with the kernel? Isn't this for some
utility that starts Aver/TV? Surely the kernel doesn't read files.

I run this same TV card in W$ and the W$ program loads firmware
and starts the card. Who's process context gets stolen to read
these files from within the kernel?

WTF? The __kernel__ doesn't read files. User mode programs
use the kernel to read files for them, on their behalf.

Truly bizarre, weird........ It's not April 1st yet!
