I thought that was disabled in standard kernel drivers in kernel 2.6 due 
to a kernel design decision that /proc wasn't suitable for this sort of 
thing, and that /sys should be used instead.  I had problems with a 
fiberchannel SAN system not being able to 'discover' new LUNs with the 
stock qlogic drivers in 2.6 (rhel4) even though this works fine in 2.4 
(rhel3)
