Nope, I installed the RedHat 9 myself and no one else has access to this machine. It's either that Redhat uses a different elevator setting for SCSI drives than IDEs or the latest Redhat updates I applied brought it to my current numbers. Besides, I believe your values may indicate an outdated system because IIRC the max_bomb_segments has been disabled and should always be zero because of some inefficiencies in the elevator algorithm.

Well, I obtains the same values for two different RH9 installation:
# uname -a
Linux XXXX 2.4.20-13.9smp #1 SMP Mon May 12 10:48:05 EDT 2003 i686 i686 i386 GNU/Linux
# elvtune /dev/hda6
/dev/hda6 elevator ID 1
read_latency: 64
write_latency: 8192
max_bomb_segments: 6# uname -a
Linux XXXX 2.4.20-20.9smp #1 SMP Mon Aug 18 11:32:15 EDT 2003 i686 i686 i386 GNU/Linux
# elvtune /dev/sda7
/dev/sda7 elevator ID 5
read_latency: 64
write_latency: 8192
max_bomb_segments: 6I'll try on my laptop.
