Tainted kernels

[Joe Zeff]

Earlier, I'd asked about what was causing abrt to claim that my laptop's 
kernel was tainted, even though I don't know of anything that would 
cause this.  Somebody asked me to check a certain location in /proc, 
which turned out not to exist on the laptop.  I'd like to check again, 
and check it on my desktop as well because I know the desktop's kernel 
is tainted by kmod-nvidia, and that would give me a good way to compare 
a known-tainted kernel with my laptop's.  Alas, I've lost the email with 
the pointer in it.  If anybody remembers what I'm supposed to check, 
please let me know.  Thanx!
