My problem was, that the system load was almost unbearable at higher speeds, but only when I was burning DAO. Do you burn DAO? Is your system load (top) also very high? Now I just upgraded to 2.4.20-pre3 and everything is just fine :-) I am not really sure if it was only the kernel, because I still have the same problem when I tell the kernel to umask the drive's IRQ (hdparm -u1). I am not 100% sure if I tried it without umask before. But without umask, everything seems to work fine now. There's just a few percent CPU load when doing c2scan or writing DAO. The only thing is that if I do a c2scan under X, X consumes all my CPU time after some time and gets unresponsive. Doing the same in the console there's no problem at all. So I am pretty sure this is a X problem and not the kernel's.
