The kernel's been doing its own symbol decoding for years now when you enable 
CONFIG_KALLSYMS.  (In fact, you have to select CONFIG_EMBEDDED to be able to 
turn it _off_.)  Thus ksymoops has been deprecated for quite some time.

Rusty Russell introduced it as part of his module rewrite in 2002:

Andrew Morton made it default to "on" in 2003:

  http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=33c59f10405afdc8

And the kernel documentation was updated to deprecate the userspace oops 
decoder back in 2005:

  http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=62a07e6e9e93e
