This is crucial: the directory is beign omitted. In plain English: it is not being moved to /usr/src at all, which is why the next command complains that it can't find r1000v_1.05 under /usr/src

Reread one of my previous post: I recommended using cp -R like so:
cp -R /home/rammsteiner/Desktop/r1000_v1.05 /usr/src

Ok, i tried what you said the "cp -R" and it worked perfectly. I then came across a problem when giving the command "make clean modules", this is how it looked:

[root@localhost r1000_v1.05]# make clean modules
make -C src/ clean
make[1]: Entering directory `/usr/src/r1000_v1.05/src`
rm -rf *.0 *.ko *~ core* .dep* .*.d .*.cmd *.mod.c *.a *.s .*.flags .tmp_versions
make[1]: Leaving directory `/usr/src/r1000_v1.05/src`
make -C src/ modules
make[1]: Entering directory `/usr/src/r1000_v1.05/src`
make -C /lib/modules/2.6.18-1.2798.fc6xen/build SUBDIRS=/usr/src/r1000_v1.05/src modules
make: Entering an unknown directory
make: *** ?lib/modules/2.6.18-2798.fc6xen/build: No such file or directory. Stop
make: Leaving an unknown directory
make[1]: *** [modules] Error 2
make[1]: Leaving directory `/usr/src/r1000_v1.05/src`
make: *** [modules] Error 2

i checked the lsmod that you put in the post you sent me, since the other guy had a problem that i could help me out. and it didnt show r1000 in it. Any suggestion?

Hey guys, i got it to work! apparently i forgot to install the devel-kernel, so i did that and everything was ok.
Thanks for all your help everyone, especially jay73.
