FC5: problem running programs off the usb drive

[Giuseppe Castagno]

Hi all,

after upgrading to FC5 from FC4 I'm no longer able to run program off
an usb drive.
It's not SELinux related, because I boot with selinux=0.
This happens both as root and as normal user.
I discovered that the new gnome-mount method is mounting my usb driver
in noexec mode:

/dev/sda3 on /media/usb-li type ext3 (rw,noexec,nosuid,nodev)

Is there a way to change this default behavior ?

TIA
