That's what I did before posting on the subject. That's why I asked where to
put hdparm -d 1 /dev/hda in /etc/rc.d since the error message comes early on
booting and putting it into rc.local it will be executed at the end of boot. I
put it into rc.S and still get the error message:

setting using_dma to 1 (on)

Further when booted with 2.6.7 kppp takes again 22 seconds to come up against
11 with 2.4.26. Therefore I resign from the idea of using kernel 2.6.7.

Signing off. Thanks everybody for the help, much appreciated.
