chmod USB pendrive problem

I've gotten my 32 meg Targus DiskOnKey USB pendrive working on Redhat Linux 9 (redhat can recognize, and mount it). But I've been having some problems with it. I originally created /mnt/diskonkey as my mount point, and I've been using
mount -t vfat /dev/sda1 /mnt/diskonkey
to mount it. Strangely enough, when I unmount and remove the pendrive, /mnt/diskonkey disappears, and reappears when I plug it back in. It also edits my fstab whenever I plug/unplug it. it adds/removes the following line
/dev/sda /mnt/diskonkey auto noauto,owner,kudzu 0 0
That much I assume is just normal working order, so I don't consider that a problem, that's just background info. Here is my problem.
when I created the mount point, I did chmod 777 /mnt/diskonkey. but whenever I mount the drive, the permissions change to 755 so I cannot edit the contents in konqueror unless I am logged in as root. I can still do functions like cp and mv in the console as root, but this is somewhat cumbersome when I am just trying to use my drive in a GUI. I've tried using chmod while it was mounted, but it gave me the following error
[root@localhost magician]# chmod 777 /mnt/diskonkey/
chmod: changing permissions of `/mnt/diskonkey/' (requested: 0777, actual: 0755): Operation not permitted
Trying to use chown to change the owner of the drive yielded a similar error as well. does anyone have a fix? The pendrive itself has no physical write-lock switch

The permissions that get set to it have nothing to do with the chmod settings of the mount point, its gotta be declared in the argument to mount. That goofiness with the mount point is all kudzu's fault.

/dev/sda1 /mnt/diskonkey vfat noauto,user 0 0

would probably be a better idea... I'm not certain how kudzu works so maybe it requires that things are mounted "owner" instead of "user". User means that any old joe user can mount the disk... and then they'll have be the owner so it'll stay 755, but your user will be the owner so R+W+X will be you and the R+X will apply to... everyone else, which is probably no one.

Also, with the above line... or the one you've got now, all you need to type is:

mount /mnt/diskonkey
