Create a fresh directory, probably somewhere you can save this
permanently since you will use it with the next kernel compile. Probably
something like /usr/src/modules/rio500/. Unpack the newer version which
is 0.7 (this looks like it supports 2.3.x kernels which is basically a
2.4.x pre), do a ./configure, then make and make install. Be certain
before doing this that /usr/src/linux/ is pointed at your 2.4.0 source
first. After the make install it should have the module in the
/lib/modules/...version.../ directory. Before you do this make sure the
old one is gone from the 2.4.0 pre module directory. It should then work
right (famous last words) with a depmod -a, unless it is incompatible
with 2.4.x.

Go for the 0.7 version.
