OK, got some more info here:
The kernel version is actually 2.2.5-15
The machine is an Olivetti Xana 53-120
hdparm -T /dev/hda gives 24.09 MB/sec (seems reasonable to me)
Trying various settings of hdparm -X n /dev/hda didn't help.

Some excertps from /var/log/messages:

FWIW, this machine is undeniably strange; the default RH6 boot disk (which uses loadlin.sys ) would cause the monitor to go into power-saving mode after loading the initrd.( I think it would continue to boot actually, but the install process is sort of difficult this way). Creating a lilo based boot disk worked fine.
