it probably does some initialization. this drill used to be the only way
to get some soundcards working: boot into win, have the vendor driver
upload some firmware, warm-reboot into linux, the firmware survives, the
linux driver is happy.

the makefile probably does depmod -ae after building and installing, and
it does not find some usb symbols in your kernel. that might be because

a) your kernel has no usb built in or as modules (quite unlikely given
you seem to use a stock redhat kernel),
b) it looks in the wrong place (do uname -a and see if you have a
/lib/modules/<kernel version> directory) and then look into the makefile
to see where it looks for the modules, or perhaps you lack a current ? try depmod -ae by hand,
c) your kernel is smp-enabled, but the module you built is not.

i'm not running redhat, so i may miss the obvious. the surest thing is
always to build your own kernel from the official sources, but that is
of course a little painful now and then...
perhaps you can use the .config file from redhat with the official
kernel tree - that way, you will get a similar basic setup (except for
some redhat-specific stuff that's missing in the normal kernel) and just
need a few tweaks.
