/proc/mtrr in 2.6

From: kernel

In 2.6, having /proc/mtrr support in a kernel run on a system which
lacks MTRR support (like my crusoe) results in /proc/mtrr existing, but
giving EIO if you try to read it. On 2.4, it is detected as not existing
and not created. Is this the new intentional behaviour, or just a bug?
