Actually the above happens when you enable CONFIG_MODVERSIONS along with
CONFIG_KMOD. The part of my patch that included the matching to versioned
kernel symbols from Richard Henderson wasn't included in 2.1.105 for some
reason.
I am waiting to see if it appears in 2.1.10x (Alan currently has it in
his diff set), and if not then I'll have to stick a __MODULE_STRING into
all the get_module_symbol calls to make versioned kernels do the Right Thing.
Paul.
