execve("/usr/bin/fusermount", ["fusermount", "-o",
"fsname=sshfs,max_read=65536,[EMAIL PROTECTED]:",
"/path/to/mountpoint" ], [/* 15 vars */]) = 0
"chmod a+s /usr/bin/fusermount" was no help.

Is there a way to trick strace into doing so? If I understood ltrace
correctly (sorry for long lines):
24757 memcpy(0x804d058, "max_read=65536", 14)
= 0x804d058
(...)
24757 strlen("rw")
= 2
24757 strlen("nosuid")
= 6
(...)
24757 sprintf(",nosuid", ",%s", "nosuid")
= 7
24757 strlen("rw,nosuid")
= 9
24757 strlen("nodev")
= 5
24757 realloc(0x804d008, 16)
= 0x804d008
24757 sprintf(",nodev", ",%s", "nodev")
= 6
24757 strlen("rw,nosuid,nodev")
= 15
24757 strlen("max_read=65536,")
= 15
24757 realloc(0x804d008, 32)
= 0x804d0f0
24757 sprintf(",max_read=65536,", ",%s", "max_read=65536,")
= 16
24757 strlen("rw,nosuid,nodev,max_read=65536,")
= 31
24757 getuid()
= 0
24757 getuid()
= 0
24757 sprintf("fd=5,rootmode=40000,user_id=0", "fd=%i,rootmode=%o,user_id=%i",
5, 040000, 0) = 29
24757 mount(0x804d0d8, 0x804d028, 0x804bcf6, 6, 0x804d058)
= -1
the mount option is
"rw,nosuid,nodev,max_read=65536,fd=5,rootmode=40000,user_id=0"
(Yes, I tried the mount request as root user in order to make sure it's
not a permission problem.)

Debian stable:
ii fuse-utils 2.2.1-4sarge2 Filesystem in USErspace (utilities)
