Probably not. It looks like it was munged by klogd. Some distributions are 
still shipping with klogd configured to destroy the original information on 
the way to the log, without even making it do a sanity check that the 
System.map it's using actually matches the current kernel.

Jeff, please disable the broken klogd symbol munging and reproduce it,
running the oops through ksymoops manually. Ksymoops should have built-in 
sanity checks on the System.map it tries to use.

Also, please make sure you report this as a serious bug with the vendor of 
whatever distribution you're running on this box.
