yay!

am i to presume from this that /dev/ksyms would properly "export" the
real symbol table from kernel, and not a simple list of "this symbol
is wrapped in this macro which makes it get stuffed into the list of
symbols that /dev/ksyms exports"?

also...will it dynamically add (or delete) symbols from lkms as they
are loaded (or unloaded)?
