Anyway, not that it really matters, but I re-did the testing with '-a0' and it
didn't help one iota. The 2.6.13 kernel on ReiserFS (without using
'nolargeio=1' as a mount option) still takes about 4m35s to fseek 200,000
times on that 4MB file, even with 'hdparm -a0 /dev/hda' in effect.
Does it make a difference when done on the filesystem *partition*
rather than the base drive? At one time, this mattered, and it may
still work that way today.
Eg. hdparm -a0 /dev/hda3 rather than hdparm -a0 /dev/hda
