 Arik,
 I had the same problem until a few minutes ago. I found out that the device 
driver for my IDE controller was not compiled in the kernel, nor was it 
available as loadable module. So my IDE device was working without DMA and 
in 16 bit mode. That was the cause for my problems. Maybe it is the same 
cause for your issue.
 I have recompiled the kernel with via82C (my chipset) support and now the 
problems are gone. The driver was found under: device drivers -> ATA -> 
via82cxxx chipset support.
 When I now run hdparm /dev/hda1 it show me that the device is operating in 
32bit DMA mode.
 I just thought to let you know in case you still suffer from this issue.
 Regards,
Michel
