No.  At least the SuSE 2.4 kernel (don't know about official 2.4 kernels) 
does implement madvise().

FWIW I also didn't see any real speedup.  time for startkde (control-C'ed 
after the splash goes away) is from 22.2-23.2 down to about 21.8 seconds.  
Time for a 'konsole -e true' (without _anything_ KDE loaded) from 7.1-8.3 
down to 6.5-7.2.  Every time with cache cleared, and on a kernel 2.6 
machine.

So, it's a bit, but not that much.  Hmm.  I hoped for something more ;)


Ciao,
Michael.
