that explains it: Your version of Linux 2.4 is missing the statistics
fields in that pseudo-file. According to `iostats.txt' of the kernel's
documentation those fields were introduced in 2.4.20, but some
distributions pulled those patches into their distribution kernels
before that. It might be neccessary to enable these statistics at (the
kernel's) compile time.

Without these fields collectd cannot obtain these statistics, and I
doubt that those fields would have been introduced, if there was another
nice interface for those values.. If you know one, however, let me know

I'm afraid you won't have much choice but upgrade to 2.4.20 (or later)
or get the patches from somewhere if IO-statistics are important to
you, sorry :/
