I'm having the same problems and I'm using the ol' 2.4.20-20.9 kernel 
with RH 9. I had to give up on my Serial to IDE convertor so now I'm 
using IDE again (I couldn't stand the 1.3 MB/sec transfer rate with the 
SiI3112 so I reinstalled using IDE). Anyway, I too am looking for a fix 
for this but it looks to me like very little if anything has changed 
since 2.4.x. My system also crashes (to say the least! I lose all access 
to my HD) when I try hdparm -X66 -d1 /dev/hdg.
