In the latter code window, you can see there is not a package whose name includes the 'fuse' string. FUSE seems to be supported by the kernel, according to these lists, but there is no package bearing the name 'fuse'. Neither do I find any reference to the version in /usr/src/linux-188.8.131.52/fs/fuse/, which holds the sources, nor in fuse.txt. Fuser has nothing to do with FUSE.
What would happen if I install FUSE 2.7.3 from Slackbuilds, which is for Slackware 12.0? I will download it and see what is in the package. Perhaps there I'll find a clue.
EDIT: insmod gives
root@darkstar:/usr/src/linux-184.108.40.206/fs/fuse# insmod fuse
insmod: can't read 'fuse': No such file or directory
Note: I could as well just have asked how does one know a kernel module version number, if it has one.
