dmraid 1.0.0-r13 does not detect RAID-0 on PDC-20267

I've got a Promise FastTrack 100 IDE Controller with two 30GB disks attached 
and configured as a RAID-0. Linux 2.4 detects the RAID using the ataraid 
kernel module. AFAIK dmraid is responsible for being able to access such 
(fake) RAID configuration from the 2.6 kernel. Unfortunately it does not 
detect my drives as belonging to a RAID. It just returns 'no RAID disks' when 
trying to set them up via 'dmraid -ay'. I would really like to get this 
going, as I want to move to a newer kernel but losing my data is not an 
option (neither is copying). I could dd the first few Kbs of each disk and 
post the files here, would that help? What else could I try? BTW: the kernel 
driver pdc20xx_old is loaded and the disks are accessable via /dev/hd[ef]
