I noticed that elvtune does not work on FC3 with a
(self-compiled, pristine) kernel. I also tried it with other 2.6.* kernels.

elvtune /dev/sde
ioctl get: Invalid argument

In fact, I get the same message for all disks, either those on a 3ware
controller, or SATA disks directly attached to the motherboard.
The hw is a dual opteron mb with 4Gb RAM.

Did this command become obsoleted?
Is there alternativ?

Not that I ever found. You can play with values in /sys/block/{device}/queue or wherever you have your sysfs mounted.
Not a great user interface, but at least you can play.
